> This issue aims to move {{replaceFunctionName(usage: String, functionName: String)}}
from {{DescribeFunctionCommand}} to {{ExpressionInfo}} in order to make {{ExpressionInfo}}
returns actual name instead of placeholder. We can get {{ExpressionInfo}}s directly through
{{SessionCatalog.lookupFunctionInfo}} API and get the real names.
