(fix): CI — pass signed flag to validateDefaultTypes for bigint defaults

validateDefaultTypes referenced an undefined $attribute variable when
checking bigint string defaults, causing testCreateAttributesBigIntValidationSignedUnsignedAndMetadata
to fail with "Undefined variable $attribute". Read signed from the
Document in checkDefaultValue and thread it through validateDefaultTypes.
