Documentation specifies defaults but they are not actually used

[Ten0]

Describe the bug

Documentation explicitly specifies that the following fields have defaults:

But they are actually not applied. If the builder doesn't explicitly specify them, they will instead be explicitly be set to None

This makes the request fail with error:

ValidationException: The provided Content Type is invalid or not supported for this model

Setting those explicitly on InvokeModelFluentBuilder avoids the error:

builder
    .accept("application/json")
    .content_type("application/json")

Hi @Ten0, thank you for reporting this! This is a bug in a Smithy model for bedrockruntime (from which aws_sdk_bedrockruntime is code generated), where the doc (which also comes from the model) mentions defaults but they are not actually used as fallback; the requests fail if nothing is specified for accept and content_type.

@jmklix Could you help bring this up with bedrockruntime so that the team is aware?
