Broken example in useAuth Usage section and index.md

[maovieira]

The current useAuth example in Usage section and packages/firebase/useAuth/index.md line 21 uses signInWithPopup with one argument but this function requires two (missing Auth argument).
Current (9.1.0):

const { isAuthenticated, user } = useAuth(getAuth(app))
const signIn = () => signInWithPopup(new GoogleAuthProvider())

Will throw an error.
Fix:

const auth = getAuth(app)
const { isAuthenticated, user } = useAuth(auth)
const signIn = () => signInWithPopup(auth, new GoogleAuthProvider())

My package.json:

  "dependencies": {
    "@vueuse/core": "^9.1.0",
    "@vueuse/firebase": "^9.1.0",
    "vue": "^3.2.37"
  },
  "devDependencies": {
    "@vitejs/plugin-vue": "^3.0.3",
    "vite": "^3.0.7"
  }
