Create a release pipeline on Azure for Windows installer (#7441)

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
