Remove old body on note and tasks (#13290)

Fixes: https://github.com/twentyhq/twenty/issues/13110

I'm deprecating note.body and task.body to remove confusion between body
and bodyV2

What will be left but should be done later to avoid breaking changes:
- re-add a body field in the graphql API only that points to the same
bodyV2 field in SQL (need to be handled in fields and filter for note
and task)
- (wait some time)
- remove bodyV2 field
