Update to Scala 3.4.0

[davoclavo]

Hello!

Here are some changes to update to Scala 3.4.0. Match types seem to be behaving slightly different now, I wonder what improvements could be adopted in the future.

Some changes:

1. Due to multiple new warnings:
   • Added infix modifier for commonly used infix operators and types - the other option is to remove the infix modifier and instead surround the infix operand with backticks
   • Replaced : _* for *
2. Due to new compilation errors:
   • Added Promotion (T, DType) => T - Although I'm still unsure what are the implications of this change everything runs properly in my machine
3. Updated SBT + Plugins in order to fix github action workflow generation
