Currently, deprecations in dependencies are silenced in Sass, however, we are aware of the fact that some deprecations are present, see the following comment: https://github.com/3scale/porta/pull/4190#discussion_r2635011699

The idea of this task is to:

• disable quietDeps and run sass compilation (e.g. rake webpack:dev)
• review all deprecations and fix them
• if all deprecations are removed, it's possible to remove quietDeps: true
