Split general git tips out of ContributorInfo.rst

[reviewed by @ben-albrecht; concept also OK’d by @lydia-duncan and @mppf]

I’ve recently been finding the ContributorInfo file to be so large and
monolithic that it’s hard to get my head around what it contains. I’m
increasingly inclined to break general information out into its own
files such that the file focuses primarily on things specific to the
Chapel workflow. In this PR, I’m putting the general information
about using ‘git’ out into its own file which reduces the main file by 40%.
