Restrict `repository_object_format` update for PUT projects/:id
What does this MR do and why?
Contributes to #462382 (closed)
Problem
optional_project_params_ce
list is used for both create and update
endpoints. However, repository_object_format
field is only supported
by create endpoints.
Solution
Move repository_object_format
field to
optional_create_project_params_ce
group, so it won't be available for
update endpoints.
