feat: accept multiple locales in fallbackLocale

[jessrynkar]

What?

This change allows fallbackLocale to accept an array of locales in find queries and locale configuration.

/** Local API **/
  await payload.findByID({
    id,
    collection,
    locale: 'en',
    fallbackLocale: ['fr', 'es'],
  })

/** REST API **/
  await fetch(`${baseURL}/api/${collectionSlug}?locale=en&fallbackLocale=[fr,es]`)

/** GraphQL **/
  await restClient.GRAPHQL_POST({
    body,
    query: { locale: 'en', fallbackLocale: '[fr, es]' },
  })

/** Locale Configs **/
  locales: [
    {
      code: 'en',
      label: 'English',
      fallbackLocale: ['fr', 'es'],
    },
  ]

Why?

This update is part of the planned localization enhancements. Currently, only one fallback locale can be specified. If that locale doesn’t contain data, the query returns nothing. To work around this, users have to inspect the response themselves and then make additional queries for other locales.

With this change, Payload handles that work automatically. Users only need to provide a list of fallback locales in their preferred order, and Payload will check each one until it finds a value.

How?

Updates query handling across the local API, REST API, and GraphQL so that fallbackLocale can accept either a string or an array of locales. When an array is passed, Payload will iterate through them in order and return the first found localized value. This behavior applies to both collections and globals.
