Fix hook config

1. Rename the hook to codee-format, which better reflects the codee format entry and is aligned with clang-format and cmake-format.
2. Drops redundant quotation marks in the YAML file.
3. Drops the args. With the current configuration, codee takes .codee-format from the root source directory and ignores more relevant format files that reside "closer" to the formatted source file (e.g. /a/file.f90 is formatted with /.codee-format instead of /a/.codee-format).
