Download Button [1/n]: Setup UI on the editor client

If the download callback is defined (not for local editor or VSCode, but will be for Gradio), then we display it and use the loading state to disable you from clicking on the button.

I'm making the signature of the callback take in an AIConfig object parameter, because we have function `clientConfigToAIConfig` within the editor pacakge: https://github.com/lastmile-ai/aiconfig/blob/c838856f36941b0796c8f12edcf846cc18ebdaa1/python/src/aiconfig/editor/client/src/shared/types.ts#L37

## Test Plan
Rebase onto #1045

Go to `aiconfig/python/src/aiconfig/editor/client` and run this command:
```
rm -rf node_modules && yarn && yarn build
```

Then go to `aiconfig` dir and run this command:
```
aiconfig_path=./cookbooks/Gradio/huggingface.aiconfig.json
parsers_path=./cookbooks/Gradio/hf_model_parsers.py
aiconfig edit --aiconfig-path=$aiconfig_path --server-port=8080 --server-mode=debug_servers --parsers-module-path=$parsers_path
```
