Describe the bug

I used to use the "FlexibleTimeWindowMode" enum to determine whether my schedules have flexible time window mode OFF or FLEXIBLE
Example:

const { FlexibleTimeWindowMode, CreateScheduleCommand } = require("@aws-sdk/client-scheduler");
        const params = {
            Name: "some_name",
            Description: "some_description",
            Target: "some_target",
            FlexibleTimeWindow: {
                Mode: FlexibleTimeWindowMode.OFF
            }
        };

        const command = new CreateScheduleCommand(params);

I can no longer access "FlexibleTimeWindowMode" in the "3.930.0" version of the aws sdk.

I have confirmed this issue is a regression. A code generation bug (fixed by smithy-lang/smithy-typescript#1787) made an older version of enums used by a subset of clients across the SDK into types-only exports.
