Update the web/drive_v2 browser and chrome samples

@damondouglas would you have any time to clean up those samples so no errors or warnings exist?

Hello @financecoding , Would after Friday be ok? I'm taking a licensing exam this Friday.

Ya, no pressure, thanks!

Hello @financecoding , I finally finished my exam today. This took me longer than expected to update my tools, etc and get back into the flow of coding again. I should be back in the zone and finish this by the end of next week.
