julia: update parser and highlights (#4035)

- Update patterns for type definitions:
  The grammar was updated to parse `abstract type` and `primitive type`
  as a single token.
- Update @symbol capture to highlight quoted operators as symbols.
- Add pattern to highlight adjoint operator.
- Update patterns and captures for:
  - "keyword" operators (in, isa, where)
  - type operators (<:, >:)
  - Parametrized types.
