build: Use hatchling as build backend

[matthewfeickert]

• Migrate to using hatchling as the build backend.
  • Include all build metadata in pyproject.toml.
  • Remove setup.py, setup.cfg, and MANIFEST.in.
  • Remove package_data as not needed.
• Remove MANIFEST check from CI.
  • Remove check-manifest install in CI workflow.
  • Remove MANIFEST check step from CI.
• Add git to Dockerfile to ensure hach-vcs can work.
• Add .git_archival.txt to add archival options to support auto versioning.

I'm unclear why this is failing for the Docker build when it worked for pyhf, but for

docker build -f docker/Dockerfile -t recast/recastatlas:debug-local .

I'm getting

12.02 Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.
12.02 
12.02 For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

Ah, it was because I forgot to ensure that git was installed in the Docker build.
