fix example query templates

[VladimirAlexiev]

The example queries at https://query.linkedopendata.eu/ have this wiki template junk on top, which makes them invalid:

{{#if:|
{{ safesubst:p{{ safesubst:#ifeq:|eq|1|2}}|{{ safesubst:p{{ safesubst:#ifeq:|
PREFIX p: <https://linkedopendata.eu/prop/>|1|2}}||}}|{{ safesubst:p{{ safesubst:#if:|1|2}}|
PREFIX p: <https://linkedopendata.eu/prop/>|}}}}{{ safesubst:p{{ safesubst:#ifeq:|eq|1|2}}|{{ safesubst:p{{ safesubst:#ifeq:|
PREFIX q: <https://linkedopendata.eu/prop/qualifier/>|1|2}}||}}|{{ safesubst:p{{ safesubst:#if:|1|2}}|
PREFIX q: <https://linkedopendata.eu/prop/qualifier/>|}}}}{{ safesubst:p{{ safesubst:#ifeq:|eq|1|2}}|{{ safesubst:p{{ safesubst:#ifeq:|

|}}}}
}}
