Fix: upgrade setuptools in tag-release workflow (#82)

The tag-release workflow was failing because the pre-installed setuptools (65.5.0) doesn't normalize package names to underscores when creating source distributions.

This caused PyPI to reject the tarball with error: 'Filename altimate-datapilot-cli-0.1.1.tar.gz is invalid, should be altimate_datapilot_cli-0.1.1.tar.gz'.

Modern setuptools (65.6.0+) automatically normalize package names. Adding --upgrade flag ensures we get the latest version that handles name normalization correctly.

Impact: This will allow both wheel and source distributions to upload successfully to PyPI.
