fixup_whats_new_pr.py

"""
This tool is used during CI testing to make sure sphinx raise no error.

During development, we like to have whatsnew/pr/*.rst documents to track
individual new features. Unfortunately they other either:
  - have no title (sphinx complains)
  - are not included in any toctree (sphinx complain)

This fix-them up by "inventing" a title, before building the docs. At release
time, these title and files will anyway be rewritten into the actual release
notes.
