Add ruby-lsp and zen packages to Brewiz catalog

[Copilot]

This PR adds two popular packages to the Brewiz package catalog based on their Homebrew info:

Packages Added

ruby-lsp (homebrew/core/ruby-lsp)

• Category: Development Utilities (devutil)
• Description: Opinionated language server for Ruby
• Homepage: https://shopify.github.io/ruby-lsp
• Tags: development, ruby, language-server

Ruby LSP is an opinionated language server for Ruby that provides IDE features like autocomplete, go-to-definition, and linting. It's designed to work with any editor that supports the Language Server Protocol.

zen (homebrew/cask/zen)

• Category: Browsers & Web Tools (web)
• Description: Gecko based web browser
• Homepage: https://zen-browser.app/
• Tags: browser, productivity, macos

Zen Browser is a privacy-focused web browser built on Mozilla's Gecko engine. It offers a streamlined browsing experience with modern features while maintaining compatibility with Firefox extensions.

Bug Fixes

While adding these packages, I discovered and fixed two compatibility issues:

1. Fixed packages-updater for Ruby 3.2+

The script was using the deprecated positional argument syntax for YAML.safe_load, which was removed in Ruby 3.1+. Updated to use the new keyword argument syntax:

# Before (deprecated)
YAML.safe_load(content, [Date, Time])

# After (Ruby 3.2+ compatible)
YAML.safe_load(content, permitted_classes: [Date, Time])

2. Fixed beautify-packages-yaml for multi-document YAML files

The script was only loading the first YAML document (the metadata header) instead of the categories array. Updated to properly handle multi-document YAML streams:

# Before - only loads first document
data = YAML.load_file(@input_file)

# After - loads all documents and finds the categories array
docs = YAML.load_stream(File.read(@input_file))
data = docs.find { |d| d.is_a?(Array) }

Testing

• All existing tests pass (2 runs, 13 assertions, 0 failures)
• YAML syntax validated successfully
• Packages are correctly sorted alphabetically within their categories
• Formatting follows repository conventions

These changes ensure the Brewiz catalog remains up-to-date with popular development tools while maintaining compatibility with modern Ruby versions.
