Fix source distribution build and upgrade CI baselines (#83)

Summary:
Source distributions never had the right version file -- they'd always fail. `bindings/python/.../version.py` is always written out when building an sdist, so try to use it if it's available.

Add a CI baseline to try using the sdist/install with KenLM

Also move to Jammy for baseline Linux images since most Focal ones are being deprecate and upgrade GHA components depending on old Node versions. v4 of these actions breaks artifact storage with dup names/doesn't merge automatically; fix this. Contents of `dist` post-upload by wheel builder/sdist becomes

### Test Plan (required)
CI + local test
```bash
pipx run build --sdist
# move tarball out of git repo where commands to fetch hashes failed
cd ${SOURCE_DIST_DIR} # after untarring
USE_KENLM=0 pip install -v .
```

Ensure CMake uses the correct executable per cibuildwheel (#48)

Summary:
See title. Using `FindPython3` in CMake >= 3.16 requires using `PYTHON3_EXECUTABLE` as the relevant flag specifying the interpreter path. This ensures that headers and modules are found in the proper subtree by CMake such that bindings are linked against the correct version of Python. Current Wheel builds link against totally spurious versions.

Pull Request resolved: #48

Test Plan: CI + CIBW, ensuring that the correct CIBW version of Python is what CMake finds at wheel build time.
