Add GitHub Release

[rtritto]

Description

When a new version is released, it must also be released as a new GitHub release.

Some advantages:

• you can enable custom watch on releases so that you'll be notified when a new release comes out
• you can easy check the release notes (the global CHANGELOG.md will be very big)

Example of an implementation is on mongo-express repository:

• .github/workflows/publish.yml
• scripts/release.cjs

Note: this feature will be nice to have with upcoming vike v1

Hi @rtritto, I agree, contribution welcome 💚

[rtritto]

Should this change be made in a new GitHub workflow or in an existing one?

Whichever you think is best at this point. Let's first focus on getting something functional, then let's see if we want to refactor it.
