@juergen-fast thank you for the contribution I have one comment: do you think it worthwhile to add this setting also for built-in server config somewhere here ? so it will have support for client/server users

[chen-keinan]

its ok to add this comment (#nosec G101) next to user / password config to overcome lint issue :
keyTrivyDBRepositoryPassword = "trivy.dbRepositoryPassword" // #nosec G101

My changes based on the githubToken-Code. I think there is no need for built-in server because in this case you have the property serverUser and serverPassword in the trivy secret here

@juergen-fast you'll need to update plugin tests with new EnvVar

I tried adding the new EnvVar but the tests still fail. I don't know how to fix them, sry
