chore: fix login image with sha release (#10157)

# Which Problems Are Solved

Fixes the releasing of multi-architecture login images.

# How the Problems Are Solved

- The login-container workflow extends the bake definition with a file
docker-bake-release.hcl wich adds the platforms linux/arm and linux/amd
to all relevant build targets. The used technique is similar to how the
docker metadata action allows to extend the bake definitions.
- The local login tag is moved to the metadata bake target, which is
always inherited and overwritten in the pipeline
- Packages write permission is added

# Additional Changes

- The MIT license is noted in container labels and annotations
- The Image is built from root so that the local proto files are used
