The wrong version is indicated for old bouncycastle artifacts features

See https://forum.xwiki.org/t/dependency-conflict-in-extension-manager-for-docx4j-importxhtml/6128 for more details.

The problem is that when Bouncy Catle moved from bouncycastle to org.bouncycastle groupid they also changed a lot the version scheme and older versions have a much greater version number...
