[Fix regression] LPS-31258 Localize "Load more results" message in Asset Categories Selector

Hi Iliyan,

I've created a fix to solve the regression: the LMR-link is not properly localized when we switch locales (i.e. add different locale key to the URL).

This regression effects both 6.2.x & ee-6.1.x.

Could you please review my changes?

Thanks,
Tibor
