fix(space-creator): check provision result before proceeding (#119)

# Issue
If the `NEXT_PUBLIC_W3UP_PROVIDER` environment variable is not set, the
app will use `did:web:web3.storage` as the default storage provider.
That works well if we are pointing to Prod environment
(https://up.web3.storage), however, if we use the Staging environment
(https://staging.up.web3.storage) it will fail to provision the space
because the default provider is invalid for Staging.

# Fix 
- Verify if the Space Provisioning result contains an error. If so,
throw the error to prevent the user from continuing the flow and
attempting to upload files.
- Updated Docs and sample Env Vars.

 If you are using `w3infra`, the service URL will be displayed as the `UploadApiStack`'s `ApiEndpoint` output once `npm start` has successfully set up your development environment.
