[@loopback/sequelize] Attempting to use `options` in a `where` filter leads to "There is no equivalent operator" exception

Describe the bug

This section of the code throws an exception if the "where" filter includes an "options" key: https://github.com/loopbackio/loopback-next/blob/96b9a56788937f081e61f1d48dc080c7233d394c/extensions/sequelize/src/sequelize/sequelize.repository.base.ts#L604

Example filter that will throw an exception:

where: {
   name: {
     like: '%abcdefg%',
     options: 'i'
   }
}

Reproduction

N/A

extensions/sequelize/src/sequelize/sequelize.repository.base.ts の604行目付近から始め、失敗している where フィルターをドキュメント化された演算子と比較します。options キーがどのように処理されるべきかを判断し、その後、サンプルのフィルターで「There is no equivalent operator」例外が発生しなくなったことを確認します。
