Set the text direction of the AI-written name and alternative text from their content

Problem/Motivation

The name and alt inputs carry no dir. On an Arabic page an English AI answer is right-aligned, and its full stop shows at the start.

Steps to reproduce

1. Open the generator in Arabic.
2. Generate with an English description.

Proposed resolution

Set dir="auto" on the AI-written name and alt inputs, and on module help text that may be untranslated, if cheap.

User interface changes

• Before (1.0.x): on an Arabic page, the English alternative text is right to left, full stop first.
  
• After (one screenshot for #3634872, #3634873 and #3634878 together): the alternative text reads left to right.
