refactor: fix runtime TypeAlias with pipe operator

Move GivenPyProjectResult type alias after PyProjectData class definition
to use unquoted modern syntax. TypeAlias with pipe operator requires
runtime evaluation, so forward references must be avoided.

Changes:
- vcs-versioning/src/vcs_versioning/_pyproject_reading.py:
  - Move GivenPyProjectResult after PyProjectData class
  - Use unquoted: PyProjectData | InvalidTomlError | FileNotFoundError | None
  - Fixes TypeError: unsupported operand type(s) for |: 'str' and 'type'

- vcs-versioning/src/vcs_versioning/_types.py:
  - PathT: os.PathLike[str] | str (unquoted)
  - Already worked since os is imported
