Tests: Remove a workaround for a Firefox XML parsing issue

mgol · web-flow · commit e7ffe1f135df · 2022-10-03T22:53:39.000+02:00
Firefox 96-100 used to report the column number smaller by 2 than it should in the `parsererror` element generated for invalid XML documents. Since that version range is unsupported now and it includes no ESR versions, the workaround can now be dropped. Closes gh-5109 Ref gh-5018
