Subject: [PATCH] Fix qbt-config-patch for Python 3.14: use lambda in re.sub
 replacements

Python 3.14 raises PatternError for backslash sequences like \P in
re.sub replacement strings. Switch to lambda replacements which bypass
that interpretation. Also pin to python:3.13-alpine to avoid future
surprises from pulling :3-alpine.
