Setting scalacOptions twice causing warnings

[ckipp01]

Give an minimal snippet like this:

// using scala 3.1.0

def foo = "bar"

Do a compile and get no warning. Check the .scala/.bloop/<build-target>.json and see that there are no options containing -feature, -deprecation, or -explain.

Change you script to:

// using scala 3.1.0
// using options -deprecation -feature -explain

def foo = "bar"

Do a scala-cli clean . just to be safe and then follow it up with a scala-cli compile . and you see the following:

Compiling project (Scala 3.1.0, JVM)
Warning: Flag -deprecation set repeatedly
Warning: Flag -feature set repeatedly
Warning: Flag -explain set repeatedly

If you now look in the bloop json file again you see that they are duplicated in options. I'd expect this not to happen so the user doesn't see these errors.
