resource_transformers/tocss: Fixed hugo:vars casting
Variables passed via the hugo:vars function where passed as type string. This caused problems when using the variables in sass functions because these expect a specific type. Now we check if the passed variables have to be quoted and therefore are of type string or if they should not be quoted and let the type interpretation up to the sass compiler. Fixes #10632
