sdist is missing `tests/__init__.py`

[mtelka]

The sdist at PyPI is missing the tests/__init__.py file and so testing fails:

__________________ ERROR collecting tests/test_compliance.py ___________________
ImportError while importing test module '/data/builds/ul-mass-rebuild/components/python/jmespath/build/amd64-3.14/tests/test_compliance.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:

Looks like a regression from switching to uv to build the sdist/whl files. I'll get this fixed and publish a new version.
