Add alias for scala

[saqib-trywe]

Currently, there isn't a defined alias for scala. I propose adding sc as that alias.

Even better would be if there was a ability to define your own aliases in preferences (like Dash).

This works for me:

1. Search for Scala
2. Enable Scala 3.2.0
3. Clear the input
4. Type "sc" followed by Tab
5. Search within Scala
