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,

                project="CMIP6",
            )

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

The pull request above has now been merged, but the REF still needs to be updated to use the new recipes.
