Automated gem/npm release workflow

[jagthedrummer]

This robustifies the .github/workflows/release.yml workflow file.

It also converts bin/bump-all and bin/release-all from bash to ruby.

It also adds npm handling to both bump-all and release-all.

TODO:

• Work with @andrewculver to get a token for RubyGems that will allow pushing of the core gems.
• Do we want to add an explicit approval step here, and then restrict approval to only admins? (Currently I believe that anyone with write access to this repo could run this workflow.)

This is still WIP but I need to get the version-bump.yml file into main so that it can be manually run. Currently these workflows don't have any side effects. (That is they don't modify a repo or release anything to rubygems or npm yet.)
