ci: fix double 'python -m python -m' from the pip-install sweep

My previous sweep regex matched 'pip install --require-hashes' even
when already preceded by 'python -m ', producing 6 lines of the form
'python -m python -m pip install --require-hashes ...'. mlirDistro
caught this immediately: the workflow itself failed to start because
the run line was malformed.

Collapse the doubled prefix back to single 'python -m'.
