AZ CLI should show error details or provide documentation on how to find error details

When a Synapse workspace command fails, instead of providing the detailed error, there's an error message that says to refer to error details for more information.

Sample error:

To reproduce:
1. Run `az synapse workspace key update --key-identifier xxx --is-active true --workspace-name xxx --resource-group xxx --name xxx` with a synapse workspace that's had encryption activated, and recently been given access to the Key.
2. Attempt to activate the workspace through this command
3. Run into an error saying to check error details that aren't visible.
