fix: update uv invocation so that 'make test' in the top-level directory runs all the tests

[rajive]

make test or make was failing as follows:

(env -u PYTHONPATH  uv run --isolated --python 3.13  python -m pytest)
      Built beangulp @ file:///Users/rajive/code/beangulp
Installed 14 packages in 9ms
/Users/rajive/.cache/uv/builds-v0/.tmpmSYVuT/bin/python: No module named pytest
make: *** [test] Error 1

The fix resolve this issue by resolving the missing dependencies --extra petl and --group test, that are defined in the pyproject.toml file.
