Looks good, some small comments below.

In other forms, we use the reset() function for this:

Suggested change

	useEffect(() => {
	setValue("documentation", project.documentation || "");
	}, [project.documentation, setValue]);
	useEffect(() => {
	reset({
	documentation: project.documentation || "",
	});
	}, [project.documentation, reset]);

Is this file necessary? There is already a max height rule on modals from bootstrap.

Something about CK editor caused the bounds of the modal to exceed the viewport size when you insert a lot of text. This style makes it behave better.

Is this needed?
