utils/lxmlize: re-raise the original parse error instead of wrapping it (#5680)

`raise Exception(e)` after the log line widened the type to bare
Exception and dropped the original traceback, so the scraper output
showed `Exception('XMLSyntaxError(...)")'` instead of the actual
parser error. Plain `raise` keeps the lxml exception and its full
chain intact.
