Add support for specifying the storage schema on the application client

[neilcampbell]

utils-ts has newly added support for specifying storage schema when calling deploy or create on the application client.
Whilst utils-py has support for specifying extra pages, it doesn't support overriding the local or global state schema.

We need to also ensure this change flows through into the Python typed client generator.

Below are the reference TS PRs.

• fix: Include schema property in create and deploy calls algokit-client-generator-ts#104
