Please Bump Version of Google Java Format to 1.15.0

This Tool and the Pre-Commit Hook is not ready for JDK 17 - please just replace 1.7 with 1.15.0, i would prefer not to have to make my own version of it for a single project.

thanks

Hi @FireRedDev, had the same issue and forked this repro to update the version and make it adjustable.
