Added a comment that require IAM configuration to Azure Blob Storage

[hiroakit]

This is a feedback.

Reason:

I tried to run the ShowCase unity project in Unity while reading the following documents:

1. https://docs.microsoft.com/en-us/azure/remote-rendering/samples/showcase-app
2. https://docs.microsoft.com/en-us/azure/remote-rendering/quickstarts/convert-model

However, I didn't realize that IAM settings required in Azure Storage, and several hours passed... On the other hand, searching carefully in docs.microsoft.com, we will find the corresponding description page:

• https://docs.microsoft.com/en-us/azure/remote-rendering/how-tos/create-an-account#link-storage-accounts

Therefore, I thought it would make the introduction smoother and save time to have the URL around RemoteObject.cs L: 691.

Hi, quick update here: To be less specific about the storage type, we decided to do the following:

• add a new troubleshooting item, specifically for 'failed to load model': https://docs.microsoft.com/en-us/azure/remote-rendering/resources/troubleshoot#failed-to-load-model
• in the tool error output, link to that entry

That way we have an extra indirection that allows us to add more troubleshooting guides in the future to the docs.

That said, you can abandon this PR, because our change will be deployed to this repo with the next release. Thanks for all your contributions, it's always very welcome!
