Bug 11619: remove duplicate key in QueryParser config

Bug 11619: remove duplicate key in QueryParser config

Corrects a double entry for language in yaml file.
Language should have been language-original.

Test plan:
Check that you have language-original in your zebra install.
Specifically, this index should cover MARC21 041$h.
Enable QueryParser and search for a record with this index.
Note that this patch does not enable searching on this
index without QueryParser. This is true for many more indexes
in record.abs that are not included in the getIndexes routine.

Works as described - make sure you are testing with a current
indexing configuration.
