feat(helm): upgrade traefik (#832)

[Alputer]

I have realized that our traefik dependency is from 3 years ago. Updating the treaefik dependency resolved the linting error. I tested it with 5 different workflows and it seems to be working fine.

Works well!

By moving from the Traefik helm chart v10.6.2 to v31.0.0 we are also moving from Traefik v2.5.4 (source) to v3.1.2 (source).

I have checked the migration guide and the changes and it seems like we are not affected by any of it, even more so because we are using k8s Ingresses and not traefik's IngressRoutes. The only change that might have affected us is the change of behaviour of PathPrefix, which does not support regexes anymore (source); we are not using regexs in router rules, so we are good.

Just some small comments:

• Could you rebase the PR against latest master?
• Could you chage the commit message to highlight that we are moving to traefik v3? Something like build(helm): upgrade Traefik to v3 (#832)
• Traefik helm chart v31.1.0 was released yesterday. Maybe we should already upgrade to this version?

I rebased and updated the commit message. I also tested the version 31.1.0 and it seems to be working fine too. So updated the version from 31.0.0 to 31.1.0.
