ci: add Go module release workflow

- Adds new go-release.yml workflow for creating Go module releases
- Renames go.yml to go-test.yml for clarity
- Improves tag pattern for FFmpeg release to be more specific
- Updates description field in FFmpeg workflow
- Adds justfile commands for Go module release management

This provides proper release automation for the Go module alongside the existing FFmpeg library release process.
