Subject: [PATCH 04/28] Hardcode the org/repository.

The organization and repository names cannot have capital letters.

Since the conditionals ensure the job only runs in the WordPress/gutenberg repository, this value can be safely hard-coded.

Subject: [PATCH 05/28] Prepare a plugin artifact for `wordpress-develop`

Because the `wp-build` package performs some substitutions, the script needs to be run with `IS_GUTENBERG_PLUGIN` set to `false` an `IS_WORDPRESS_CORE` set to `true`.

 commit message:

Publish the built plugin zip.

This adds a job to the Build Gutenberg Plugin Zip workflow that publishes the built zip to the GitHub Container Registry.

# This is the commit message #2:

`always()` check is necessary.

# This is the commit message #3:

Don't use arrays for `include` combinations.

# This is the commit message #4:

Adjust job names so it's clear what's being done.

This ensures the "Build Release Artifact" name is preserved when the assets are built for the Gutenberg plugin because that is a check that is required to be passing before a merge is allowed.

# This is the commit message #5:

Correct typo in environment variable.

# This is the commit message #6:

One more typo fix.

Subject: [PATCH 08/28] # This is a combination of 5 commits. # This is the 1st
 commit message:

Change the package name to be more specific.

# This is the commit message #2:

Change the package name on GHCR.

Even though it's nested under the `gutenberg` repository, `wordpress-develop-build` could be confusing.

# This is the commit message #3:

Correct other relevant conditionals.

# This is the commit message #4:

Workflow file can be simplified now.

With better type casting to avoid truthy false values, the workflow can be less cautious.

# This is the commit message #5:

Fix one missed conditional.

+## Using Environment Variables to Control Behavior
+
+In some scenarios, it can be helpful to change how the build script works through environment variables. This is particularly useful within CI/CD workflows.
+
+The following environment variables can be used to override `wpPlugin` properties.
+
+| Environment Variable     | `wpPlugin` Property |
+|--------------------------|---------------------|
+| `WP_PLUGIN_NAME`         | `name`              |
+
+### Example
+
+Here is an example job for a GitHub Actions workflow file that uses environment variables to change behavior:
+
+```yaml
+build:
+	name: Build ${{ matrix.plugin-name }} plugin
+	runs-on: 'ubuntu-latest'
+	permissions:
+		contents: read
+
+	strategy:
+		matrix:
+			plugin-name: [ 'my-plugin', 'my-plugin-premium' ]
+
+	steps:
+		# Perform other steps to prepare for buildling (checkout repository, install dependencies, etc.)
+
+		- name: Build plugin
+		  run: npm run build
+		  env:
+			  WP_PLUGIN_NAME: ${{ matrix.plugin-name }}

 ## Contributing to this package
 
 This is an individual package that's part of the Gutenberg project. The project is organized as a monorepo. It's made up of multiple self-contained software packages, each with a specific purpose.

 ### Enhancements
 
-- Introduced the `WP_PLUGIN_NAME` environment variable for overriding `wpPlugin.name` ([#75844](https://github.com/WordPress/gutenberg/pull/75844)).
 - Avoid unexpected results when typecasting `IS_GUTENBERG_PLUGIN` and `IS_WORDPRESS_CORE` values to Booleans ([#75844](https://github.com/WordPress/gutenberg/pull/75844)).
 - Skip PHP transforms during builds when building for WordPress Core ([#75844](https://github.com/WordPress/gutenberg/pull/75844)).

-## Using Environment Variables to Control Behavior
-
-In some scenarios, it can be helpful to change how the build script works through environment variables. This is particularly useful within CI/CD workflows.
-
-The following environment variables can be used to override `wpPlugin` properties.
-
-| Environment Variable     | `wpPlugin` Property |
-|--------------------------|---------------------|
-| `WP_PLUGIN_NAME`         | `name`              |
-
-### Example
-
-Here is an example job for a GitHub Actions workflow file that uses environment variables to change behavior:
-
-```yaml
-build:
-	name: Build ${{ matrix.plugin-name }} plugin
-	runs-on: 'ubuntu-latest'
-	permissions:
-		contents: read
-
-	strategy:
-		matrix:
-			plugin-name: [ 'my-plugin', 'my-plugin-premium' ]
-
-	steps:
-		# Perform other steps to prepare for buildling (checkout repository, install dependencies, etc.)
-
-		- name: Build plugin
-		  run: npm run build
-		  env:
-			  WP_PLUGIN_NAME: ${{ matrix.plugin-name }}

 ## Contributing to this package
 
 This is an individual package that's part of the Gutenberg project. The project is organized as a monorepo. It's made up of multiple self-contained software packages, each with a specific purpose.
