esmvaltool/enso-basic-climatology diagnostic not configured for CMIP7 datasets

[k-a-webb]

Despite enso-basic-climatology being marked as CMIP7 ready in #536, the diagnostic script is only configured for CMIP6 datasets.
While the recipe will run successfully for CMIP7 datasets, no output is produced (and since Climate-ref v0.16.0 an error is raised when attempting to copy the output from scratch/ to results/; see below)

See https://github.com/ESMValGroup/ESMValTool/blob/324d4ebaa8c1420fdc09a40818fbe1a36754d773/esmvaltool/diag_scripts/enso_metrics/climatology_diagnosticlevel2.py#L156:
if metadata["project"] == "CMIP6":

A similar issue is in the diagnostic enso-characteristics: https://github.com/ESMValGroup/ESMValTool/blob/324d4ebaa8c1420fdc09a40818fbe1a36754d773/esmvaltool/diag_scripts/enso_metrics/enso_diag1metrics.py#L541-L556

        for var_prep in var_preproc:
            obs += select_metadata(
                input_data,
                variable_group=var_prep,
                project="OBS",
            )
            obs += select_metadata(
                input_data,
                variable_group=var_prep,
                project="OBS6",
            )
            models += select_metadata(
                input_data,
                variable_group=var_prep,
                project="CMIP6",
            )

@bouweandela Has anyone from ESMValTool looked at an updated ENSO diagnostic?
