[Split out from T373746: Wikifunctions' function editing page doesn't explicitly specify lang and dir attributes for every input field.]

We use Codex's Chip input for aliases, but it currently (Feb 2025) only lets us wrap each chip in a specific dir, and the input similarly.

This is probably(?) blocked by work upstream at T383788: [Timebox] Consider how to provide improved directionality support for Wikifunctions.

• Each chip gets the right dir and lang attribute
• The input for each ChipInput is set to the expected dir for the relevant content language (not interface language)
