please.sh: retire the finalize function

This logic was used in Azure Pipelines to finalize the release notes
before releasing new Git for Windows versions.

These days, that job is performed elsewhere, specifically in
https://github.com/git-for-windows/git-for-windows-automation/blob/56d8604016d6/update-scripts/tag-git.sh#L55-L62

So let's retire that function (and some support functions, too).
