Request: Build documentation without starting shell

I would the ability to generate documentation without opening a shell.

Motivation: I would like to cache the documentation in a docker image layer so I do not have to generate it every time I start the container.

Suggestion: A flag that builds documentation without starting the shell. `aws-shell --no-prompt` ?

No file or test is named in the issue. Start by locating the documentation-generation entry point and the code that starts the interactive shell; verify how the proposed --no-prompt behavior should build documentation without opening the shell and confirm the result can be reused in a Docker image layer.
