enable_types_contributor setting allows arbitrary values except boolean

[IlyaRyzhov]

Bug description:
hypersistence.utils.enable_types_contributor setting can hold arbitrary values except boolean. For, instance "abc" string. Moreover, setting hypersistence.utils.enable_types_contributor to true has no effect - type contributor is still disabled

To Reproduce:
Apply settings listed below

hypersistence:
  utils:
    enable_types_contributor: abc

Expected behavior:
I expect to get some exception, indicating that the setting hold invalid value.

Additional context:
I guess the problem is this code snippet io.hypersistence.utils.hibernate.type.HibernateTypesContributor (or more specifically in Boolean.getBoolean call):

 Boolean enableTypesContributor = (Boolean) configurationService.getSetting(ENABLE_TYPES_CONTRIBUTOR, value -> {
            if(value instanceof Boolean) {
                return value;
            }
            if(value instanceof String) {
                return Boolean.getBoolean((String) value);
            }
            throw new HibernateException(
                String.format("The value [%s] of the [%s] setting is not supported!", value, ENABLE_TYPES_CONTRIBUTOR)
            );
        });
