feat(#47): add action for releases

[kalebpace]

What this does

Defines a Release action which is triggered by new tags:

• creates a release
• builds all projects in the examples directory for three platforms Windows, Linux, Mac and two archs arm64 and amd64
• archives them
• uploads and attaches them to the release

How to use

• Create a tag locally and push
• Create a tag through the Github UI
  • Do not create a release, the action does this for you.
• If a project is added/removed from the examples directory, update the .goreleaser.yaml config to reflect this.

Example runs

• Runner: https://github.com/kalebpace/polyform/actions/runs/12334867496
• Release: https://github.com/kalebpace/polyform/releases/tag/v0.17.2
