nbstripout already strips metadata.kernelspec from .ipynb files, but jupytext .py files can accumulate kernelspec blocks (display_name, language, name) that leak local environment details into the repo. This adds a new pre-commit hook (strip-py-kernelspec) that automatically removes these blocks from doc/**/*.py files. Also strips existing kernelspec blocks from the 21 files that had them.

Summary
bstripout\ already strips \metadata.kernelspec\ from .ipynb\ files, but jupytext .py\ files can accumulate kernelspec blocks (\display_name, \language,
ame) that leak local environment details into the repo.
This adds a new pre-commit hook (\strip-py-kernelspec) that automatically removes these blocks from \doc/**/*.py\ files.
Changes
Motivation
Discovered during PR #1633 review — a contributor's local kernelspec (\pyrit-dev) was committed via a jupytext .py\ file. This hook prevents it from happening again.
