prerelease should be set automatically

Currently, the prerelease needs to be set manually in the release workflow which makes it brittle to mistakes. We should set the prerelease to true based on semantic versioning and introduce a new option to opt-in to this behavior.

Start by reading the repository's release workflow and identify where prerelease is currently set manually. Check how semantic versioning is represented there, then define the opt-in option and verify that prerelease becomes true for prerelease versions while existing behavior remains unchanged.
