Make a tag-based push to nuget/github release for this repo

[Chet Husk]

Should basically be the same as either

• FSAC: https://github.com/fsharp/FsAutoComplete/blob/main/.github/workflows/release.yml
  • manual trigger
    or
• KeepAChangelog : https://github.com/ionide/KeepAChangelog/blob/main/.github/workflows/publish.yml
  • automatic on tag

[Chet Husk]

This is done.
