GreengrassException builder returns exception of a wrong type

[Illapikov]

Describe the bug

Currently GreengrassException builder returns an object with incorrect type. It returns AwsServiceException instead of GreengrassException.
Which in turn forces unnecessary casting (GreengrassException) GreengrassException.builder().build() and doesn't seem in line what other exceptions do.

Regression Issue

Expected Behavior

GreengrassException exception = GreengrassException.builder()
        .message("not found")
        .statusCode(404)
        .build();

to compile without an error

Current Behavior

GreengrassException exception = GreengrassException.builder()
        .message("not found")
        .statusCode(404)
        .build();

produces a compilation error

incompatible types: software.amazon.awssdk.awscore.exception.AwsServiceException cannot be converted to software.amazon.awssdk.services.greengrass.model.GreengrassException

Reproduction Steps

Given the actual behavior produces compilation error, the following code should be sufficient for reproduction:

GreengrassException exception = GreengrassException.builder()
                .message("not found")
                .statusCode(404)
                .build();

Possible Solution

I don't have much experience with generated code, but looking at the BadRequestException from the same package, there's a difference in Builder interfaces:

BadRequestException:

public interface Builder extends SdkPojo, CopyableBuilder<Builder, BadRequestException>, GreengrassException.Builder

vs
GreengrassException:

protected static class BuilderImpl extends AwsServiceException.BuilderImpl implements Builder

Note that BadRequestException builder works correctly, when built it returns BadRequestException and not GreengrassException, the parent one.

After looking a bit deeper, CopyableBuilder is what provides T build() method, which makes BadRequestException to return correct type.
