// Updates a Lambda function's code. If code signing is enabled for the function,
// the code package must be signed by a trusted publisher. For more information,
// see Configuring code signing for Lambda (https://docs.aws.amazon.com/lambda/latest/dg/configuration-codesigning.html)
// . If the function's package type is Image , then you must specify the code
// package in ImageUri as the URI of a container image (https://docs.aws.amazon.com/lambda/latest/dg/lambda-images.html)
// in the Amazon ECR registry. If the function's package type is Zip , then you
// must specify the deployment package as a .zip file archive (https://docs.aws.amazon.com/lambda/latest/dg/gettingstarted-package.html#gettingstarted-package-zip)
// . Enter the Amazon S3 bucket and key of the code .zip file location. You can
// also provide the function code inline using the ZipFile field. The code in the
// deployment package must be compatible with the target instruction set
// architecture of the function ( x86-64 or arm64 ). The function's code is locked
// when you publish a version. You can't modify the code of a published version,
// only the unpublished version. For a function defined as a container image,
// Lambda resolves the image tag to an image digest. In Amazon ECR, if you update
// the image tag to a new image, Lambda does not automatically update the function.
