Creating github action to perform automated releases

[axsaucedo]

Creating issue following discussions with @zhimin-z on #324 proposal.

This encompasses a github action that performs releases every week / month, namely a workflow with:

• Tagging date / week
• Changelog generator
• Convert MD to PDF with pandoc
• Create release
• Attach changelog and PDF to release
• Publish release

This would be a high priority as it would make such a difference.

Continuing on #390
We need to change back the action name since we do not have these two github actions so it won't work.

Closed via #357

@zhimin-z this is done for security reasons, you can now find the forks in the EthicalML org as best practice to avoid injection of malicious code (which is why the action works atm) - this repo also has protection to avoid running external github actions
