Provides Fabric API 0.73.0

• Bump version The beta is real! (not 5.0.0-beta.2 though, it's a fake! a poser! an imposter! a sussy baka! a liar! a mistake!) (Ennui Langeweile)

• Update to QSL v4.0.0-beta.8 (Ennui Langeweile)
• Fix Lifecycle Events' QMJ being accidentally too strict (Ennui Langeweile)
• Update to QSL v4.0.0-beta.7 Yeah, this is a rare case of Fabric's API technically being a superset of QSL's equivalent, but considering how the superset works? Yeah, I'm definitely much happier with QSL's approach here (which was old Fabric's one) than this one; Oh, this commit will fix a heckton of bugs as well, watch as this single-handely makes QFAPI a beta! (Ennui Langeweile)
