Bug Report: Dynamic property method calls in @noSelf classes incorrectly use colon syntax (:) instead of dot syntax (.)

```ts
/** @noSelf **/
declare class testClass {
  static [key: string]: () => void;
  static testFunction(): void;
}


testClass.testFunction();
testClass.testKey();
```
```lua
testClass.testFunction()
testClass:testKey() -- Incorrect
```
