Description

The clusters are currently running Kubernetes 1.23 which went EOL on 2023-02-08. Kubernetes 1.31 is running in production (wikikube) since July 2025.
It's time to upgrade since we plan on moving to the next (>1.31) Kubernetes version already and we aim to support not more then two versions at the same time.

I discussed with @LSobanski about fitting this in Q3 or Q4 planning.

We'll confirm a realistic timeline at SRE Summit and update after.

Unless anything unexpected happens, @elukey will handle this towards the end of the quarter.
