Subject: [PATCH] ogcapi-images: Avoid ServiceException in WFS GetCapabilities

`STACItemFeaturesResponse.getCapabilitiesElementName()` throws
an `UnsupportedOperationException` instead of returning `null`,
producing a `ServiceExceptionReport` when requesting a WFS 1.0.0
`GetCapabilities` document.

`null` is a valid return value for this method, that results
in `WFSGetFeatureOutputFormat.getCapabilitiesElementNames()`
not contributing an output format name for the
`WFSGetFeatureOutputFormat` in question.
