Warn if a selected metadata type is not supported by selected API version
In the custom filters dialog, if you select a metadata type that is not supported by the API version, the compare and deploy currently just silently ignores that item, giving the impression that the compare has failed. e.g. selecting "Duplicate rule" with metadata version prior to 38.0.
It would be good for Gearset to provide a warning if a selected metadata type is not supported by the selected API version.
