Replace deprecated google types package

[robertparascabulbthings]

Hello, guys!

A couple of days ago the package used for types became deprecated and it was replaced by another package with almost the same name.

I hope the solution provided in the PR is fine by you. 😄

Current package (deprecated): https://www.npmjs.com/package/@types/googlemaps New package: https://www.npmjs.com/package/@types/google.maps
