Seems like it should be named {{numItems}} not {{numitems}}. Not sure how the wrong capitalization got into the Polish .xtb file (it's the only occurence of that capitalization in our entire repo).

The case was incorrectly changed in Transifex during l10n. Corrected it in Transifex: https://www.transifex.com/brave/brave/translate/#pl/$/156854308?q=text%3A{{numitems}}
