docs: Add a pointer to the git post-receive hook

I had to stumble upon this feature before I realized it was here
inside the tools directory all along. This documentation should make
it easier for the next person coming along looking for a patchwork git
hook.

+7. Optional: Configure your VCS to automatically update patches
+
+    The tools directory of the patchwork distribution contains a file
+    named post-receive.hook which is an example git hook that can be
+    used to automatically update patches to the Accepted state when
+    corresponding comits are pushed via git.
+
+    To install this hook, simply copy it to the .git/hooks directory on
+    your server, name it post-receive, and make it executable.
+
+    This sample hook has support to update patches to different states
+    depending on which branch is being pushed to. See the STATE_MAP
+    setting in that file.
+
+    If you are using a system other than git, you can likely write a
+    similar hook using pwclient to update patch state. If you do write
+    one, please contribute it.
