Bump dependency versions

Mostly in prep for 1.19.4.

 - Update to Loom 1.1.

   - Simplifies our handling of remapped configurations a little.
   - Removes the need for a fake fabric.mod.json in the API jar.

   For reasons I don't quite understand, this required us to bump the
   Fabric API version. Otherwise interfaces are not injected.

 - Update to Rollup 3.0.

 - Do NOT update NullAway: It now correctly checks @Nullable fields in
   inherited classes. This is good, but also a pain as Minecraft is a
   little over-eager in where it puts @Nullable.
