Clean up some places missed by #7544.
Found this when running test farm tests. They were working as of 5d90544, and I will truly shocked if subsequent changes (all to the windows installer) made them stop working.
* Release script needs to target new CHANGELOG location
* Clean up various other CHANGELOG path references
* Update windows paths for new certbot location
* Add certbot to packages list for windows installer
This PR creates a pipeline triggered on tag push matching v0.* (eg. v0.40.0).
Once triggered, this pipeline will build the windows installer, and run integration tests on it, like for the pipeline run nightly.
I also add a simple script to extract from CHANGELOG.md file to extract the relevant part to put it in the body of the GitHub release. I believe it makes things nicer.
* Create release pipeline
* Relax condition on tags
* Put beta keyword
* Update job name
* Fix release pipeline
