Minor future proofing commands but i'd also like to make a request:

goreleaser check is returning errors and deprecations. While we're here I'd like to expand scope a small amount such that we have a repeatable process for these kinds of updates.

• Ensure the configuration is valid per goreleaser check
• Document these checks in our release process (if applicable)

Besides that - as a practice I'd like to start capturing "how does a reviewer perform review of these changes" in our PR descriptions -> I'll work this into a PR template.

Added a GitHub Action that will run GoReleaser check on any pushes or PRs that contain a change to the .goreleaser.yaml file.

Also tweaked the wording a bit in our release documentation to call out the brew info and the action. We don't go too in-depth into distros.
