refactor(frontend): 非推奨となったReactivity Transformを使わないように (#12539)

* refactor(frontend): 非推奨となったReactivity Transformを使わないように

* refactor: 不要な括弧を除去

* fix: 不要なアノテーションを除去

* fix: Refの配列をrefしている部分の対応

* refactor: 不要な括弧を除去

* fix: lint

* refactor: Ref、ShallowRef、ComputedRefの変数の宣言をletからconstに置換

* fix: type error

* chore: drop reactivity transform from eslint configuration

* refactor: remove unnecessary import

* fix: 対応漏れ
