Migrate Renarde with new migration script

[gsmet]

@FroMage here is the result of the new migration script.

Could you make sure it addresses the concerns you expressed?

• It transforms the documentation
• It transforms the codestarts (but you will have to update the snapshots by yourself if you have codestarts tests - IIRC, it prompts you to use something like -Dsnap to refresh them automatically)

I wasn't able to build it as, apparently, there are some changes around multipart handling but I think it has nothing to do with the migration process itself.

Obviously, don't merge this PR :).

Ah, I wondered if this should be handled by the migration tool or not, it's RR who moved classes around for 3.x, do you think it should? Or is this only for jakarta?

As for the rest, LGTM :)

It could be handled if it's just classes being moved around. Can you list me the transformations that should be made with old class -> new class? I'll have a a look.
