perf(scala): use scala-cli first to avoid timeout

[wahtique]

Description

• update Scala module to try first to retrieve the current version with scala-cli and fallback to current ( slower ) scclac
• update utils.rs mock commands to call scala-cli and get back the current Scala version 3.4.1 before scalac which returns ... 2.13.5 ... . Keep them distinct for clearer testing.

Motivation and Context

Partial fix to #5583

scalac --version has some noticeable ( most likely jvm ) startup time. Depending on the computer, this can cause a timeout. scala-cli version --scala usually has little to no startup time since it is either compiled to a native binary or use its own embedded GraalVM. It also outputs exactly and only the version number which avoids some string parsing.

This can only be considered a partial fix as scala-cli is not a hard requirement to work with Scala whereas scalac is.
