According to Nixpkgs manual[1] and NixOS 23.11 Release Note[2], the
`sourceRoot` attribute passed to `stdenv.mkDerivation` should be
specified as `"${src.name}"` or `"${src.name}/subdir"` when `src` is
produced using `fetchgit`-based fetchers.
`sourceRoot = "source"` or `sourceRoot = "source/subdir"` is based on
the assumption that the `name` attribute of these pre-unpacked fetchers
are always `"source"`, which is not the case. Expecting constant `name`
also makes the source FODs prone to irrelevent hashes during version
bumps.

Implements a hook, that checks whether all dependencies, as specified by
the wheel manifest, are present in the current environment.
Complains about missing packages, as well as version specifier
mismatches.
This modifies the pypaBuildHook to not propagate its own python dependencies into the build environment. This prevents package conflicts.
- modify pypa-build-hook.sh to call pyproject-build via an absolute path. This removes the need of putting the dependencies inside the hook's propagatedBuildInputs
- remove the hook's dependencies from propagatedBuildInputs
- add a passthru test to the hook testing for the fix
