cate-desktop unsupported driver GML

[dzelge]

Expected behaviour:

Allow or don't allow GML data format when using the read_geo_dataframe operation

Actual behaviour:

When chosing GML as input data format I get the follwing error:

@dzelge This is a known problem. Could you please remove "GML" from the possible value set.
We might add "GML" later or by plugin.
