replace deprecated RulesDefinitionXmlLoader

[API Changes / Release 9.0](https://docs.sonarqube.org/latest/extension-guide/developing-a-plugin/plugin-basics/#api-changes)
* Deprecated: `org.sonar.api.server.rule.RulesDefinitionXmlLoader` is deprecated. Use the sonar-check-api to annotate rule classes instead of loading the metadata from XML files.
* use own `RulesDefinitionXmlLoader` to continue with XML format
