The enumeration list of the OUTPUT_TYPE parameter values of the 
native:createconstantrasterlayer processing algorithm (like for other 
algorithms) is specified in the documentation of such algorithm at 
https://docs.qgis.org/3.28/en/docs/user_manual/processing_algs/qgis/rastercreation.html#advanced-parameters 
and it it not intended to be the same as the Qgis::DataType enum class.
