.azure-pipelines needs an update too or is @zooba taking care of that?

Do we need to update Doc/tools/templates/customsourcelink.html:7 for the docs as well?

You forgot:

.azure-pipelines/ci.yml:4:trigger: ['master', '3.9', '3.8', '3.7']
.azure-pipelines/pr.yml:4:pr: ['master', '3.9', '3.8', '3.7']

.github/CONTRIBUTING.rst:7:- master
.github/PULL_REQUEST_TEMPLATE.md:19:If this is a backport PR (PR made against branches other than `master`),
.github/PULL_REQUEST_TEMPLATE.md:28:GH-NNNN refers to the PR number from `master`.

.travis.yml:24:    - master

Do we need to update Doc/tools/templates/customsourcelink.html:7 for the docs as well?

I suggest to restrict this PR to CI files, to be able to merge it quickly. But yeah, it sounds like this file should be updated as well.
