[PATCH 4/5] Make instructions for automatic signing more reliable

[Konstantin Ryabitsev <konstantin.ryabitsev@linux.dev>]

From: Paul Barker <paul@pbarker.dev>

We can't assume that the git directory path is '.git' from the root of
the source tree. For example, this is not the correct path if patatt is
checked out as a git submodule. We should use `git rev-parse --git-dir`
to reliably determine the git directory path. We should also surround
the path in quotes in case the user has cloned patatt in a path
containing spaces.

 If everything is working well, you can start automatically signing all
 outgoing patches sent via git-send-email::
 
-    $ echo 'patatt sign --hook "${1}"' > .git/hooks/sendemail-validate
-    $ chmod a+x .git/hooks/sendemail-validate
+    $ echo 'patatt sign --hook "${1}"' > "$(git rev-parse --git-dir)/hooks/sendemail-validate"
+    $ chmod a+x "$(git rev-parse --git-dir)/hooks/sendemail-validate"
