Migrate to io.hypersistence:hypersistence-utils-hibernate:6 types

[AlekSimpson]

What's changed?

This introduces a fix for updating @Type annotations with the proper JSON arguments.

What's your motivation?

#3 and PR #7

Anything in particular you'd like reviewers to focus on?

The import statement for io.hypersistence.utils.hibernate.type.json.JsonType does not get added in for some reason. Also the typeDefsAnnotationIsNotRemovedWhenHypersistenceUtilsAreNotBeingUsed() test now fails. My fix for the other test does not yet check if @Type is being used before removing @TypeDefs. I tried playing around with using preconditions to check for this ahead of time. That didn't quite work out though. I think maybe some sort of cursor messaging is needed for this but maybe there is a better?

Anyone you would like to review specifically?
