Don't remove graphhopper git repo in docker build

[jtbaker]

@HarelM this was my oversight in #41. We need to use the git tags later on to determine whether to build the latest tagged image in .github/build-and-upload.sh, so shouldn't rm -rf ./graphhopper/ in build.sh.

Thanks for taking care of this! I hope this will push a tagged image automatically.

@HarelM looks like 10.2 build made it onto the dockerhub registry with both platforms successfully. Let me know if you see any issues on your end, since this is the first "prod" release I suppose using this new build system.

Sure, thanks! I'll keep monitoring.
I activated the build manually today instead of waiting for tomorrow to see if this gets uploaded.
If the instructions for 10.2 are incorrect feel free to update the readme as well, I'm still not using this version in my production site...
