Deploy latest loaders version (> v3.4)

This creates sentry issues otherwise since the (new) lister is providing extra arguments the current loader do not understand in their current released versions. See [1] for example.

Plan:

• Include D7827 (one less issue)

• Bump python3-swh-loader.core

• Upgrade all python3-swh.loader* (and scheduler, storage dependencies as well, some client code change in there)

• Restart loader services (swh-worker@loader*)

• Tag grafana

• Clean up sentry issues

• [1] T4237
