Removes the part about squashing commits from the CONTRIBUTING file.
We no longer require that because github squashes commits when merging.
This will cleanup the CONTRIBUTING file a bit which is already quite
dense.
- add format target to Makefile.toml that actually fixes the formatting
- rename fmt target to lint-format

- rename typos target to lint-typos
