Update generated code for v495

When interpolating a Time object in a String, Ruby calls `to_s` under the hood.

For Rails applications defining a `default` string format, this triggers deprecation warnings as of v7.0.7: https://github.com/rails/rails/pull/48555

This change fixes that by explicitly formatting the timestamp (using the same `YYYY-MM-DD HH:mm:ss` format currently implicitly used).
