Remove javascript style comments

Remove Javscript style comments from typescript. Block comment need to annotate the type that is explicitly declared.

See example below

```js
  /**
   * Modal actions for saving or canceling profile picture changes.
   * @constant
   * @type {JSX.Element}
   */
```
