Merge PR #297 (fix GitHub issue/PR templates) into GEOS-Chem 14.1.1

This PR fixes some problems with the GitHub issue and PR templates. Namely:

1. The PR template is now .github/PULL_REQUEST_TEMPLATE.md

2. Added .github/ISSUE_TEMPLATE/config.yml to prevent blank issues and add a link to the GC manual at RTD.

This is a zero-diff update, as only code in the .github folder was touched.
