chore: enable stable PyPI workflow, fix dtype claim in README

- Uncomment pypi.yaml with tightened tag pattern 'v[0-9]+.[0-9]+.[0-9]+' so rc/dev tags only trigger TestPyPI, never production PyPI.
- Fix README 'Native dtypes' bullet: clarify uint16 stays uint16 in TorchGeo tensors; xarray promotes only when NaN fill required. Signed-off-by: print-sid8 sidsub94@gmail.com
