Update l10n for 1.85.x (Chromium 143). (#32503)
* Fixes replacement map.
Some languages use non-breaking whitespace intead of regular space in
XTB files, so our map wasn't matching. Replaced spaces to \s in the map
patterns.
* Fixes error printing.
* Adjust ICU strings validation pattern.
* Fixes <br> -> <br/> tags.
* Updated l10n for 1.85.x release.
