Fix CVE-2024-40635

[stefanprodan]

@matheuscscp in TestOCIRepository_objectLevelWorkloadIdentityFeatureGate we call update in a loop then we update again the same object so the test will randomly fail due to the update race.

--- FAIL: TestOCIRepository_objectLevelWorkloadIdentityFeatureGate (0.89s)
    ocirepository_controller_test.go:3073: 
        Expected success, but got an error:
            <*errors.StatusError | 0xc00a25dae0>: 
            Operation cannot be fulfilled on ocirepositories.source.toolkit.fluxcd.io "ocirepository-reconcileddpm8": the object has been modified; please apply your changes to the latest version and try again
