[Feature Request] Version tag in ghcr images

[xnuk]

Description

I've been struggled with building keyboard firmware in GitHub Actions for many times. I can pin the repository qmk/qmk_firmware to a commit hash, but because I cannot pin qmk/qmk_cli to something, reproducible builds aren't possible. So every revisit of my keyboard firmware broke the build.

Currently qmk_cli image in ghcr has only one tag called latest, so I hope something like version tags exist.
