[Enhancement] Add a github action to comment on issues for contribution

Similar to https://github.com/parse-community/parse-dashboard/issues/2040#issuecomment-1037933687

• Add a comment when a new issue opened.
• Add a comment when the issue is stale for 15 days.
• Close the issue if it is stale for 30 days.

Thanks.

[Triage] Good idea. I'm wondering are there existing App that we could install to fulfill this? I found this existing Actions might be useful https://github.com/marketplace/actions/close-stale-issues
