Allow to set TransformAmiVersion

[martinber]

Describe the feature you'd like

As I understand it, now it is possible to set TransformAmiVersion when launching transform jobs with the AWS SDK (see for example TransformResources in the boto3 docs). I think it is not yet possible to set this parameter while using the Transformer (or at least it's not specified in the docs)

I need it because I want to start using TransformAmiVersion=al2-ami-sagemaker-batch-gpu-535.

How would this feature be used? Please describe.
Depends on how you want to make the parameter available, for example:

transformer = Transformer(
    base_transform_job_name="",
    model_name="my-model",
    instance_type="ml.g4dn.2xlarge",
    transform_ami_version="al2-ami-sagemaker-batch-gpu-535"
    instance_count=1,
    strategy="SingleRecord",
    assemble_with="Line",
    output_path="s3://.../out.json",
    env={
        "MODEL_SERVER_TIMEOUT": "7200",
        "LOCAL_WEIGHTS_PATH": "/opt/ml/model/model.pth",
        "MODEL_SERVER_WORKERS": "1",
    },
)
transformer.transform(
    data="s3://.../in.json",
    data_type="S3Prefix",
    split_type="Line",
    job_name="my-job",
    compression_type=None,
    content_type="application/jsonlines",
    model_client_config={
        "InvocationsTimeoutInSeconds": 3600,
        "InvocationsMaxRetries": 0,
    },
    logs=False,
    wait=False,
)

Describe alternatives you've considered
Otherwise I have to stop using this library and use boto3 directly

Additional context
When launching a transform job with Transformer() and printing nvidia-smi I see it is still launching with TransformAmiVersion=al2-ami-sagemaker-batch-gpu-470:
