* feat: Updates sample to use marker anchor option.

Change-Id: Id685454421924fa708f2478d8edc58132f2500e5

* Change Google Maps API version from alpha to weekly

* Remove unnecessary newline in index.ts

* Remove newline

* Remove ts-ignore for custom marker definition

Removed TypeScript ignore directive for better type safety.

* Remove TypeScript ignore comment for marker

* Adds ts-ignores to anchorLeft and anchorTop lines.

The ts-ignores were added because we don't have typings yet.
