refactor!: remove ability for formatter list to disable autoformat

I realized that there are so, so many possible features people would
want when configuring the autoformatter, but it's better to just code it
up yourself rather than try to create a config language that can
describe all possible logic. Also adding new docs to provide examples of
more advanced autoformat logic.
