fix(lint action): Fail linting action if formatting would have happen…

…ed (#73)

We weren't using `--check` before, so this adds it. This will make the
linting actions fail if the changes aren't properly formatted.

Tested by: This should fail the linting action! If it does because of
required formatting, then this is good to go.
