json files should be usable in .d.ts files without breaking things

Suggestion

As a .json file is a static resource, it should be able to be referenced in a global.d.ts file for example without that file being automatically treated as a module. The reason for this is that a .json file may be used to simply enforce valid translation keys, and you shouldn't need to suck the whole .json file into the transpilation process to do that.

Use Cases

Example:

import translations from "../assets/translations/en-AU.json"
type $translate = {
    instant: (translationKey: keyof typeof translations) => string,
    use: Function,
    proposedLanguage: Function
}

The downside of the current method again is that the translations file is output in the transpilation process, which is wasteful if the file is large.

What the above code snippet is trying to achieve, should be allowed in a .d.ts file without breaking global declaration functionality.

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript / JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. new expression-level syntax)

まず、global.d.ts、.d.tsファイル、../assets/translations/en-AU.jsonを含む例を再現し、その後、現在、宣言ファイルとJSONインポートがどのように扱われているかを調べます。完了条件は、グローバル宣言を壊したり、JSONをトランスパイル出力に不必要に含めたりすることなく、その例から翻訳キー用のJSONを参照できることです。
