Merge pull request #312 from renovate-bot/renovate/com.gradle-common-custom-user-data-maven-extension-2.x

[Misc] Use static access with "org.apache.commons.lang3.StringUtils" for "capitalize", as reported by SonarQube (java:S3252)

  * Provide a fallback in case of parsing a resource reference missing
    information, to avoid getting IndexOutOfBoundsException error

[Misc] We don't need to trigger xwiki-rendering monthly since it's already the case of xwiki-commons

* update tests
