Upstream individual localization changes #166552

We need to upstream the fixes from

• Fix issue #156954: Wrong dateHelpText in MaterialLocalizationIt #161889
• Fix korean cupertino datepicker datetime order #163850

Otherwise the script will just overwrite them every time.

Context: #166496

These are individual changes that altered the format of some date information to match native behavior. I don't think we should go about altering these in the translation console, because I do not think they are inaccurate, they just reflect a unique platform result in a given component. We might want to approach this by altering the script to reapply these small changes after pulling from the console.
