Microsoft.Synapse workspaces/keys needs better info about "name"

The "name" field for Microsoft.Synapse/workspaces/keys is required to be the name of the key being used for the activation. The documentation only shows that this is a string value, but from the REST API you can kinda tell that it has to be the keyName.

Please update the docs to show that this needs to be the key name and not some random string. I worked for 3 days before figuring it out.

Locate the Microsoft.Synapse/workspaces/keys REST API specification and find the documentation for its required "name" field. Update the description to state that it must be the keyName of the key used for activation, then verify the generated documentation reflects that requirement.
