Support cron execution

[thewtex]

Thanks for implementing and sharing this nice Action 🙏 👏

Currently, the action will fail on forked pull requests per the GitHub Action permission limitations:

• https://help.github.com/en/actions/configuring-and-managing-workflows/authenticating-with-the-github_token#permissions-for-the-github_token
• starter-workflow template gives Resource not accessible by integration actions/labeler#12

Could it be possible to run in a scheduled mode, i.e. cron, by examining open pull requests and labelling them?

Or, not fail when the required permissions are not available?

Thanks @thewtex! I will look into both points, not failing when perms are not available should be pretty quick but having the option to use the scheduled mode seems a better solution overall.

In the meantime PRs are of course welcome :)

The first part should be done, the action will always succeed, but log an error if something failed in the process.

I'll look into the cron next.

@srvaroa awesome, thank you!! 🙏

@thewtex this one should be addressed by #26
