Describe the New Feature

dtcenter/MET#2669 adds a new dependency on the Proj library (recommend using the latest Proj version 9.2.1).

This issue is to update the METbaseimage to include the proj libraries to facilitate the compilation of MET for GitHub actions. This can be accomplished as follows:

1. Update METbaseimage to fully switch over to the Debian base image. That version is currently available on DockerHub as dtcenter/met-base:v2.0_debian. And we've been using that base image for MET development for > 6 months.
2. Complete the transition by

• Replacing Dockerfile with the contents of Dockerfile.debian
• Replace Dockerfile.debian_unit_test_env with the contents of Dockerfile.unit_test_env
• Updating the file names used in the GHA job

3. Make sure that MET's compile_MET_all.sh script and corresponding tar file has been updated to support the compilation of Proj. Note that Enhance METbaseimage to compile the ecKit and Atlas libraries #13 will soon add support for ecKit and Atlas.
4. Tag this repository with version 2.1 which will push a new METbaseimage version.

Including this issue on the MET-12.0.0 Development project since this change relates directly to the compilation of MET.
