Missing `includeDeprecatedInputValues` for `apollo client:download-schema`

I'm encountering an issue where the input field definition marked as deprecated is not present after I download the schema from the endpoint.

Upon investigating, it appears that there is a flag available for iOS and Kotlin users to include deprecated input values. See [documentation](https://www.apollographql.com/docs/ios/code-generation/codegen-configuration/#2-graphql-introspection).

Is there a similar option that I can utilize for download-schema?

Start at the `apollo client:download-schema` command entry point and review how it obtains the schema from the endpoint. Compare the documented iOS and Kotlin behavior for including deprecated input values. Done means the command has a clear equivalent option and downloaded schemas include deprecated input field definitions when it is enabled.
