Documentation website not being updated from fork PRs

[zachcran]

Describe the bug
The CI to update the documentation website is not triggering succeeding (example) when a PR is merged into master. When this is fixed, #39 should also be fixed, since that documentation generation will likely go in the same workflow.

Expected behavior
The documentation website should be updated when a PR is merged to master. The API documentation should also appear.

After looking at the action logs, it appears that the CI might just not be succeeding when the PR is from a fork. It complains about permissions, so it could be an issue with secrets and access rights between the fork and main repo.
