Blocked by the initial sorting of the locale data after #2265

• infra: implement inactive locales content generation enhancement #2265

Potentially relevant implementation details in #2265 (comment).

Same as with the language aware letters. I can extend the previos compare function to be numeric aware:

const arr = ['B', 'A', 'Å', 'Å9', 'Å11']
const sorted = arr.toSorted((a,b) => a.localeCompare(b, undefined, { numeric: true }));
console.log(sorted); // ['A', 'Å', 'Å9', 'Å11', 'B']

i tried a draft implementation at #2906 - this is imperfect, but gives you an idea of the scope of the likely changes if this is done.
