Cats 2.3.0

Welcome to the first stable release of Cats on Scala 3… milestone 2! We will continue releasing minor versions within the 2.3.x lineage against Scala 3.0.0 until it reaches a final stable release. The decision to push a stable release of Cats in advance of this date was made in order to simplify versioning within the downstream ecosystem.
