Provide a code action to replace a string with a template string

Suggestion

Provide a code action on a string to replace the string with a template string.

Use Cases

Often you start with a normal string and notice that it should better be a template string. See the example below. When the cursor is inside the string, there should be code action provided 'Replace with template string'

The code action replace the string with a template string

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. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

issue には実装ファイルもテストも指定されていません。まず TypeScript の既存の code-action エントリーポイントとテストを見つけ、次に提供されている通常の文字列の例を入力ケースとして使用してください。通常の文字列内にカーソルがあるときに「Replace with template string」が提示され、実行時の動作を変更せずに変換が適用されれば完了です。
