Fix wildcard Scala 3 imports

[keynmol]

Honestly just opening this to learn how to contribute, I know naught about writing good tree-sitter grammars.

As a source, I used https://docs.scala-lang.org/scala3/reference/syntax.html#lexical-syntax

Code:

import tools.nsc.classpath.{given Test, given Test2, Test3}
import bla.{*, given}

Before:

import_declaration [0, 0] - [0, 59]
  path: stable_identifier [0, 7] - [0, 26]
    stable_identifier [0, 7] - [0, 16]
      identifier [0, 7] - [0, 12]
      identifier [0, 13] - [0, 16]
    identifier [0, 17] - [0, 26]
  import_selectors [0, 27] - [0, 59]
    identifier [0, 28] - [0, 33]
    ERROR [0, 34] - [0, 38]
      identifier [0, 34] - [0, 38]
    identifier [0, 40] - [0, 45]
    ERROR [0, 46] - [0, 51]
      identifier [0, 46] - [0, 51]
    identifier [0, 53] - [0, 58]
import_declaration [1, 0] - [1, 21]
  path: identifier [1, 7] - [1, 10]
  import_selectors [1, 11] - [1, 21]
    ERROR [1, 12] - [1, 14]
    identifier [1, 15] - [1, 20]

After:

(compilation_unit [0, 0] - [3, 0]
  (import_declaration [0, 0] - [0, 59]
    path: (stable_identifier [0, 7] - [0, 26]
      (stable_identifier [0, 7] - [0, 16]
        (identifier [0, 7] - [0, 12])
        (identifier [0, 13] - [0, 16]))
      (identifier [0, 17] - [0, 26]))
    (import_selectors [0, 27] - [0, 59]
      (type_identifier [0, 34] - [0, 38])
      (type_identifier [0, 46] - [0, 51])
      (identifier [0, 53] - [0, 58])))
  (import_declaration [1, 0] - [1, 21]
    path: (identifier [1, 7] - [1, 10])
    (import_selectors [1, 11] - [1, 21]
      (import_wildcard [1, 12] - [1, 13])
      (import_wildcard [1, 15] - [1, 20]))))

• Should I try to match some EBNF? I'd imagine Scala 2 and Scala 3 have different grammars name-wise

Gentle ping @maxbrunsfeld as I believe you're the only one that can merge any of these prs.

[ckipp01]

Couple months later, one more attempt. Anything holding this back from getting merged in? There are a few open prs that would be great to get added and to get support for some Scala 3 features.

Sorry for the delay; thanks @keynmol .
