Add support for Scala 3.3 LTS

[csubj]

Description

Add support for Scala 3.3.0

• Add the build and repository definitions for Scala 3.3.0
• Add an extra set of tests for Scala 3.3.0

Motivation

• To stay as close as possible to the head of Scala and to provide a base for LTS.
• To make new features in Scala 3.3 available to developers.

Followed the steps of #1465 and the changes pass those tests but I think it's probably not exhaustive nor complete. I computed the dep SHA256 with a tool I hacked together and updated the values. If people are interested I can make my tool a bit more complete for managing and updating the artifact dict and publish it somewhere.

I'm not sure I have the ability to re-run the build but I believe the failure is unrelated to changes, perhaps someone can give it a kick for me

@csubj Thanks for adding this! Does scalatest-compatible work for you with scala 3.3? I get a sha256 mismatch:

Checksum was 9283e684d401d821a4cbb2646f9611cbbcd7828d2499483d13a4b507775a4cd7 but 
wanted 7e5f1193af2fd88c432c4b80ce3641e4b1d062f421d8a0fcc43af9a19bb7c2eb

The 928... checksum is what I see when I do

wget https://maven-central.storage-download.googleapis.com/maven2/org/scalatest/scalatest-compatible/3.2.16/scalatest-compatible-3.2.16.jar
shasum -a 256 scalatest-compatible-3.2.16.jar
