restore: Set deployment_name as required

The deployment_name from the AWXRestore CR doesn't requires to set a
value for this parameter.
That parameter is already required for the AWXBackup CR so it should be
the same for AWXRestore.

Creating an AWXRestore CR without deployment_name set results in a failure
during the Secrets restoration.
