fix: correct the clang-format example hgrc so that it actually works

There are three changes here:

*   Remove -i from `command`, it causes fix to eat your file and empty it out
*   Add `set:` to pattern, otherwise this is interpreted as just a glob
*   Switch `listfile:` to `include:`; `listfile:` is relative to the current
    working directory, while `include:` is relative to the repo root. This makes
    it so that you don't receive errors when running outside of the repo root
    about being unable to find the file.
