Scrivito SDK v1.18.0 がリリースされた！が...、どうやら Rails 6 をスキップしているようなのでかなり難しそう...💦 (担当チームから許諾ももらっているので一旦 #1388 を進めた方が良いかも?)

Scrivito for Rails SDK 1.18.0 Released

Earlier Rails versions are no longer supported by Scrivito. Note that during the upgrade you will need to migrate from Rails 5.2 (with Scrivito 1.17.0) directly to Rails 7.0 (with Scrivito 1.18.0).

Rails 6.x にアップグレードしたのと #1541 と #1268 #1506 で scrivito 関連の Gem を削除したので、クローズします。
