refactor: use unquoted modern type annotations in version template

Remove quotes from type annotations. With 'from __future__ import annotations',
all annotations are automatically deferred, so no quotes needed.

Changes:
- vcs-versioning/src/vcs_versioning/_dump_version.py:
  - tuple[int | str, ...] instead of "tuple[int | str, ...]"
  - str | None instead of "str | None"
  - Cleaner, more readable syntax
  - Works with mypy 1.11.2 checking Python 3.8

Result: Simpler, cleaner generated version files using modern Python syntax.
