Add custom keymap for GMMK2

it's like moved from and old repo cuz i couldn't figure out how to fork
the keychron one even though i had the original forked. it's a whole
story

Update from 2024: I just wanna say, those were the days, my Git
workflow would just be copying the changes from an old repo when I wanted
to change something with remotes. I understood even less about Git than
I do now. I find it really funny now. I'm probably gonna find this
commit message sometime in the far far future and laugh at myself even
more. Life is wild. I wonder what were the choices that led to me
journaling in a commit message of a qmk_firmware fork.
PS: the original commit message also had really weird formatting, I
fixed that but left the rest of it untouched, I wanted to preserve it
for its historical value.
