aws-sdk-js-v3: Bad types after smithy upgrade

Checkboxes for prior research

• I’ve searched for previous similar issues and didn’t find any solution.

Describe the bug

Here are 2 examples of some issues I am experiencing with types with 3.363.0

I scanned through https://github.com/aws/aws-sdk-js-v3/blob/main/CHANGELOG.md and can’t find anything that makes these seem like intentional changes, sorry if this is all a bit vague but maybe someone with more information can ask more pointed questions/add something that helps.

3.362.0 is all good, 3.363.0 has all sorts of issues. The only change that seems relevant to me is https://github.com/aws/aws-sdk-js-v3/pull/4873

Issues I see with @aws-sdk/s3-request-presigner:

Argument of type 'S3' is not assignable to parameter of type 'Client<any, ServiceInputTypes, MetadataBearer, any>'.
  The types of 'middlewareStack.add' are incompatible between these types.
    Type '{ (middleware: InitializeMiddleware<ServiceInputTypes, ServiceOutputTypes>, options?: (InitializeHandlerOptions & AbsoluteLocation) | undefined): void; (middleware: SerializeMiddleware<...>, options: SerializeHandlerOptions & AbsoluteLocation): void; (middleware: BuildMiddleware<...>, options: BuildHandlerOptions & ...' is not assignable to type '{ (middleware: InitializeMiddleware<ServiceInputTypes, MetadataBearer>, options?: (InitializeHandlerOptions & AbsoluteLocation) | undefined): void; (middleware: SerializeMiddleware<...>, options: SerializeHandlerOptions & AbsoluteLocation): void; (middleware: BuildMiddleware<...>, options: BuildHandlerOptions & Abso...'.
      Types of parameters 'middleware' and 'middleware' are incompatible.
        Types of parameters 'next' and 'next' are incompatible.
          Type 'InitializeHandler<ServiceInputTypes, ServiceOutputTypes>' is not assignable to type 'InitializeHandler<ServiceInputTypes, MetadataBearer>'.
            Type 'ServiceOutputTypes' is not assignable to type 'MetadataBearer'.ts(2345)

Issues I see with @aws-sdk/client-s3:

Property 'Body' does not exist on type 'GetObjectCommandOutput'.ts(2339)
