[Docs] Restructure of Git Best Practices doc (#7231)

* Add "Resynchronizing an Out-of-Sync Git Branch" doc

* Update (Git) Best Practices doc title and filename

* Rename Branch Resync doc

* fork Best Practices doc into multiple files

* Add the doc list to Git Best Practices doc

* Update sidebar

* Update internal references

* Update sidebar - add subsection

* Update Your Fork's Master page title

* title case on Git Best Practices main doc

* ... and in the Resynchronizing a Branch doc

* Please read Part 1

I worked really hard on this, okay?

* Please use branches, too.

* suggestions by mtei

* change note about adding multiple files

* note that the name given the remote repo is arbitrary

* suggestions by fauxpark

* Git Best Practices -> Best Git Practices

Reads more naturally.

* rephrase hint block regarding remote name

* rework the resynchronization instructions per mtei

* use hint boxes for reference to Part 1 doc

I may be addicted to hint boxes. I'm sorry fauxpark. :cry:

* add some clarity about the upstream repo

* wordsmithing per mtei

* restyle the shell code blocks

Makes them more consistent to the other docs in this section.

+# Best Git Practices for Working with QMK
+
+## Or, "How I Learned to Stop Worrying and Love Git."
+
+This section aims to instruct novices in the best ways to have a smooth experience in contributing to QMK. We will walk through the process of contributing to QMK, detailing some ways to make this task easier, and then later we'll break some things in order to teach you how to fix them.
+
+This section assumes a few things:
+
+1. You have a GitHub account, and have [forked the qmk_firmware repository](getting_started_github.md) to your account.
+2. You've set up both [your build environment](newbs_getting_started.md#set-up-your-environment) and [QMK](newbs_getting_started.md#set-up-qmk).
