fix(analyzer): remove erroneous anchor in Italian driver license regex (#1899)

The regex for U1-format Italian driver licenses had an erroneous ^ anchor
that prevented matching when the license number was not at the start of
the string. This fix removes the anchor so licenses like U1K711J11M are
correctly recognized regardless of position in text.
