./script/trigger-release (#10589)

Add `./script/trigger-release {nightly|stable|preview}`

This command can be run regardless of the state of your local git
repository, and it
either triggers a workflow run of `bump_patch_version.yml` (for
stable/preview) or
it force pushes the nightly tag.

Also add some docs on releases to explain all of this.
