Add args to prettier hook

[totoroot]

Add pretty much all available options/command line arguments to the prettier hook.

See all CLI flags for prettier here.
See all options for prettier here.

That both --write and --ignore-unknown were set to true by default, deviates from prettier's default behaviour.
Especially defaulting to overwriting files by setting --write seems unwanted for a pre-commit hook so the default is now set to false.

--ignore-unknown can be set via option now, but also defaults to false.

The output option was removed in favour of having check and list-different as separate options.
check defaults to true, so that prettier can be used sensibly as a pre-commit hook.

If a user prefers the output format of list-different, they now have the option to enable it.

Added a patch file by accident. Removed it.

All introduced options were thoroughly tested.
Ready for review.
