Deprecate Bicep CLI parameters using camel case

[shenglol]

Added new CLI parameters that use kebab case to replace the existing ones using camel case. While those parameters with wrong casing have been excluded from the help message, their implementation remains intact to facilitate a soft deprecation process. A warning message will be printed if any of the deprecated parameters are used by the user.

Closes #12117.
