fix: github pat in documentation examples

[dotdc]

Description

Close #422

This will fix the GitHub PAT in the documentation examples.

Changes in the documentation:

• Using a custom PAT everywhere, seems required, even for public repositories.
• Using CUSTOM_GITHUB_PAT everywhere as GITHUB_* are reserved secrets names.
• Bumped the actions versions

Remark

For automation please see closing-issues-using-keywords

@dotdc thanks a lot for the PR related to the version updates.

I don't think the former example with ${{ secrets.GITHUB_TOKEN }} is not working. Maybe I do not fully understand your issue #422

Within this repository am using those examples as actions. Please check #422 for some links to the related workflow runs.

If the former example is working, maybe we add a further example public with PAT?
