Add --credential parameter to bicep publish.

Related to #5753.

bicep publish behaves the same way as the insert resource function when signed in with different credentials in Azure CLI, Azure PowerShell and VSCode Azure extension. It will try to use the first credential based on my credentialPrecedence.

Describe the solution you'd like
I would like to see a --credential parameter added to bicep publish that allows me to specify the credentials to use without having to logout or change the credentialPrecedence.

Example:
bicep publish storage.bicep --target br:mymodules.azurecr.io/modules/storage:v1 --credential azurecli

Also related to #5696. If we support "insert resource" in the Bicep CLI, we would also want this credential selector there.
