Make "sonar-devon4j-plugin" compatible with SonarQube 10.4 "DownloadOnlyWhenRequired" feature

[agigleux]

Hello,

I'm Alex, Product Manager at Sonar.

SonarQube 10.4 will come with a feature to only download Sonar analyzers and 3rd-party plugins when they are really required by the Scanner. To make this feature work, each analyzer or 3rd-party plugin should declare the list of languages on which they expect to raise issues through a new MANIFEST property called Plugin-RequiredForLanguages.

See https://community.sonarsource.com/t/the-sonarscanners-download-only-required-3rd-party-plugins/108156 for more details.

Regards
