scala-library 3.8.0 support

**Problem**
Scala 3.8.0 nightly and later in-sources the scala-library for the use by Scala 3, as opposed to using Scala-2.13-bound standard library.
This means that we will run into situations where scala-library should NOT align with scala-reflect, which might exist transitively.

**Solution**
Adjust the csrSameVersions rule for Scala 3.8 so it will only try to keep scala-library and scala3-library versions aligned.
