fix: avoid shadowing of 'resource' and 'err' in machinery scaffold

Renamed the parameter 'resource' to 'res' in the WithResource function to avoid
shadowing the imported package. Also replaced ':=' with '=' when assigning to
'err' to prevent redeclaration and shadowing of the existing error variable.
These changes improve code clarity and follow Go best practices.
