[Missing Documentation] - Please document in README whether the Amazon Linux 2023 kernel is used for Lambda

[joshtriplett]

(Apologies in advance in the likely case that this is the wrong place.)

There are a variety of requests people have for the Lambda and Fargate kernel configuration. Does the amazon-linux-2023 project provide the kernel for that, or is that owned elsewhere?

Could the README please document whether this is the right place for issues with the Lambda kernel configuration, and if not, please point people towards the correct place for that?
