gh-69405: Automate creation of idlelib/help.html from Doc/.../idle.html

[StanFromIreland]

I think this would be the best way to keep it consistently synced.

secrets should already be set up as it is used in stale.yml

Pushing to PR's won't work. Two other options

• Push to main after idle.rst is modified (current)
• Fail if idle.rst is modified and help.html is not in sync

2nd Option POC

name: Check if Lib/idlelib/help.html is in sync with Doc/library/idle.rst on: push: paths:-"Doc/library/idle.rst" jobs: check-help-html: runs-on: ubuntu-latest steps:- uses: actions/checkout@v4 with: fetch-depth:0 persist-credentials:false- uses: actions/setup-python@v5 with: python-version: '3.x' - name: Bild and copy run: | cd Doc make venv make html cd .. python -c "from Lib.idlelib.help import copy_strip; copy_strip()"- run: | if ! git diff --quiet Lib/idlelib/help.html; then exit 1

@terryjreedy What do you think? An action that fails if the file is out of sync and it would be on the submitter to modify it, like is expected for clinic, config etc.?
