[prettier] detect changed files from relative dir

Previously, `yarn prettier` didn't write changed files since `glob` produced 
paths relative to cwd and `git diff --name-only` produced paths relative to git 
root directory. 

This changes `git diff --name-only` to `git diff --name-only --relative`
