Disable historical_data_enabled in SQLAlchemyInstallationStore / SQLite3InstallationStore

I'm migrating from FileInstallationStore to SQLAlchemyInstallationStore for storing credentials and don't want to store old installation records when the app is reinstalled.

With FileInstallationStore I used the flag for disabling historical records to do this. I'm trying to accomplish the same with SQLAlchemyInstallationStore and the SDK does check if a previous installation for the team exists and updates the existing record if so. However, in determining if a previous installation exists it requires an exact match on installed_at: https://github.com/slackapi/python-slack-sdk/blob/cf225995b722739f11bc530cc6a9263a44bd4b7a/slack_sdk/oauth/installation_store/sqlalchemy/__init__.py#L148

This guarantees that reinstalls always create a new record instead of updating the existing one since the install dates will always be different. I'm wondering if this is a bug or if its expected behaviour and there's some other way we're supposed to handle reinstalls.

slack_sdk/oauth/installation_store/sqlalchemy/init.py の、関連する installed_at の検索箇所から始め、履歴レコードの扱いを FileInstallationStore および SQLite3InstallationStore と比較します。再インストールのマッチングに historical_data_enabled がどのように影響すべきかを判断してください。再インストールが想定される非履歴動作に従い、新しいレコードを必要としなければ完了です。
