doc/Interesting-Taps-&-Branches: rename to Interesting-Taps-&-Forks

This document lists Tigerbrew and Linuxbrew as interesting forks, not
branches (they used to be "Interesting Branches (aka forks)" but that
changed in b7455469), so "Interesting Taps & Branches" is a more fitting
title.

The term "branches" is also presumably confusing to folks with a shallow
understanding of GitHub and/or git who may not realize how GitHub forks
and git branches are related.

 A Tap is homebrew-speak for a git repository containing extra formulae.
 Homebrew has the capability to add (and remove) multiple taps to your local installation with the `brew tap` and `brew untap` command. Type `man brew` in your Terminal. The main repository https://github.com/Homebrew/homebrew-core, often called `homebrew/core`, is always built-in.
