Refactor `PeerId::default` to strip prerelease tags from version

[artrixdotdev]

With #144 about to be merged, I noticed an issue where the PeerId tests failed specifically for the Tortillas ID, the problem being that when the version is 0.0.0-alpha-commit the alpha text gets put into our PeerId, which can result in conflicts, and a myriad of other issues. before #144 can get merged, we need to strip the alpha de-notion, and the commit hash from the ID when calling PeerId::default
