fix(codewhisperer): disabled setting looks enabled in workspace scope #3683

Problem:
Uncheck the "Code Whisperer: Share Code Whisperer Content With AWS" setting at the user level, but when showing settings at workspace level it's checked, even though nothing specific is actually in the workspace settings file.
#3477

Solution:
Define the setting as "application" scope.
