🪲 [Fix]: Fix an issue where prereleases was not created during (#51)

## Description

- Reestablish functionality to run `Publish-PSModule` during PR. Used to
create prereleases of a module before it is published with a release
version.
- Revert: #37. This should have been reverted in the following PR,
seeing as it was for nightly runs/adhoc runs. The `CI.yml` template was
added just after which rendered this change unnecessary.
- It still remains to find a way to perserve the functionality, but not
need a pipeline to do it. I.e. a prereleaser "chat" bot that takes
commands from maintainers in the comments of the PR.
