Oudated link for user object properties

[creme332]

Affected page: https://firebase.google.com/docs/auth/web/manage-users

Issue

The comments in the first two snippets in the Get the currently signed-in user section have a dead link:

  // User is signed in, see docs for a list of available properties
  // https://firebase.google.com/docs/reference/js/firebase.User

Snippets for both Web version 9 and 8 are affected.

@creme332 good catch, thanks for reporting it!

The correct links should be:

• v8: https://firebase.google.com/docs/reference/js/v8/firebase.User
• v9: https://firebase.google.com/docs/reference/js/auth.user

I'll get those comments fixed :)
