[Feature Request] Better locales typing in i18n-util.ts

[Zer0xxxx]

Version

5.26.2

Describe the bug

Currently:

export const locales: Locales[] = [
  'en-US',
  'fr'
];

Reproduction

Would be better to codegen:

export const locales = [
  'en-US',
  'fr'
] as const;

Or:

export const locales = [
  'en-US',
  'fr'
] as const satisfies readonly [string, ...string[]];

Demo:

^ We can see the inlay hint is perfectly typed here.

Could also be codegen as:

export const locales = [
  'en-US',
  'fr'
] as const satisfies readonly Locales[];

(Even if it could be pointless to use Locales here, depending on the reliability of the codegen.)
