Add validation configuration/mapping XSDs for 3.1 version #217
Description
https://github.com/jakartaee/validation/tree/main/src/main/xsd does not include XSDs for Jakarta Validation 3.1. While there were no changes in this area, it would be good to have the XSDs there, even if just for the 3.1 in the XMLs:
<validation-config
xmlns="https://jakarta.ee/xml/ns/validation/configuration"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="https://jakarta.ee/xml/ns/validation/configuration https://jakarta.ee/xml/ns/validation/validation-configuration-3.1.xsd"
version="3.1">
<property name="smth">value</property>
</validation-config>
and if we do so, the XSDs should be available through https://jakarta.ee/xml/ns/validation/
