Fix deserialization of old decorations values 

The deprecated `window.decoration` values `true` and `false` were using
the `visit_bool` visitor for serde. However, only the `str` visitor was ever
called.

To print the correct deprecation notice, the bool visitor has been
removed and the warning has been added for the `"true"` and `"false"`
str visitor.
