Share Button [7/n]: Display loading UI

Created a separate component for the shareButton to manage the `isLoading` state and show that in the UI

## Test Plan
Rebase on then do: #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
```
