PT: wrong reference to taxonomy

[TomazErjavec]

ParlaMint-PT.xml (and ParlaMint-PT.ana) has: https://github.com/clarin-eric/ParlaMint/blob/5d55e6a0a63e6b6ce5047142df6236dbfd2ecae4/Samples/ParlaMint-PT/ParlaMint-PT.xml#L111 we have now common taxonomies, so it should be <catRef scheme="#ParlaMint-taxonomy-parla.legislature" target="#parla.uni"/>

@matyaskopp , strange that your factorise script didn't change than. Or maybe it was never run...
