[DevOps]: Add a GitHub workflow that bumps the version and drafts a GitHub tag/release #809
Description
Is your feature request related to a problem?
It is tedious to checkout a branch on main, push the branch, run tbump, open a PR, then merge the PR. This can be automated across all of the E3SM tools too (e.g., e3sm_diags, e3sm_to_cmip, zppy, zstash)
