feat(releases): automatically run `buildit` and `builditmac` workflows upon releases and upload the artifacts

[xnus-kernel]

This PR proposes a change to the buildit.yaml and builditmac.yaml GH action workflows; now they're dispatched upon releases being:

• Created;
• Published;
• Prereleased; and
• Edited[^1].

It also removes the workflow_dispatch condition. If necessary, the workflow_dispatch condition can be added in again, for convenience sake – however it won't upload the artifacts to the release, of course.

[^1]: please do note that with this to properly compile latest upstream source, the tag must be updated to the specific commit SHA (i.e: git push -f <REMOTE> <SHA>:<TAG>), as well as removing the old binaries, of course.
