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
