docs/FAQ: tap homebrew/core before editing formula

Browse Source 
New installs don't tap `homebrew/core`, so `brew edit foo` fails with
`Error: Invalid usage: foo doesn't exist on disk.` for any package.
Add an instruction to run `brew tap homebrew/core` first, which fixes
this issue.

## Can I edit formulae myself?
Yes! It’s easy! Just `brew edit <formula>`. You don’t have to submit modifications back to `homebrew/core`, just edit the formula to what you personally need and `brew install <formula>`. As a bonus, `brew update` will merge your changes with upstream so you can still keep the formula up-to-date **with** your personal modifications!

Note that if you are editing a core formula or cask you must set `HOMEBREW_NO_INSTALL_FROM_API=1` before using `brew install` or `brew update` otherwise they will ignore your local changes and default to the API.
