Inclusion of rename organization api (#33303)

This adds an endpoint (`/orgs/{org}/rename`) to rename organizations.

I've modeled the endpoint using the rename user endpoint --
`/admin/users/{username}/rename` -- as base.

It is the 1st time I wrote a new API endpoint (I've tried to follow the
rename users endpoint code while writing it). So feel free to ping me if
there is something wrong or missing.

Resolves #32995
