Editorial: Reword loop in ValidateAndApplyPropertyDescriptor

[nicolo-ribaudo]

Minor tweak to avoid a false positive when linting for re-declared parameters (ref tc39/ecmarkup#679, #3768)

[nicolo-ribaudo]

Ecmarkup interprets the first variable name after "For each" as a variable declaration. We could fix it in Ecmarkup for this specific case, but it's easier to tweak our wording instead.

This is an improvement, so approving. But should we revisit #3406? Let's talk about it in the editor call.

I'd be happy with #3406, but happier still with driving from the table that we already have.

Worth pointing out that 402 has [[<var>]] as an editorial extension for dynamic field access, if used sparingly (they don't) I think it's an improvement over doing field access using prose like this.

I would prefer to avoid introducing the [[<var>]] syntax to 262. Generally I would like to minimize the amount of novel notation in the specification.
