ci: switch to releaser-pleaser (#906)

Switch to releaser-pleaser[0] for planning new releases.
This adds the following new features:

- We can easily cut pre-releases, these are always useful if we want to
allow some customers to test features before making an official release
or to validate changes made to the release CI workflows
- We can add our own release notes to each release to better inform
customers about the new features we added or about any deprecations.
