Add new K8S versions to tests

[jbpaux]

What this PR does / why we need it:
Kubernetes released new upstream version (1.26) and all distros were updated to take it into account.
This PR also updates the previous minor versions where applicable.

Special notes for your reviewer:
I've updated also a few things:

• In 1.26 containerd must be updated as CRI v1alpha2 was removed.
• Logic for node taints was changed to take into account all next versions of Kubernetes (was quite static in current implementation)

If applicable:

• this PR has an associated PR with documentation in akri-docs
• this PR contains unit tests
• added code adheres to standard Rust formatting (cargo fmt)
• code builds properly (cargo build)
• code is free of common mistakes (cargo clippy)
• all Akri tests succeed (cargo test)
• inline documentation builds (cargo doc)
• all commits pass the DCO bot check by being signed off -- see the failing DCO check for instructions on how to retroactively sign commits

@jbpaux can we remove Kubernetes version 1.21 and 1.22 from the test matrix as they have now reached end of life: https://endoflife.date/kubernetes. We are aiming to remove EOL versions each time we add the latest. @adithyaj, would you agree with this?

[jbpaux]

@kate-goldenring I've removed old Kubernetes versions in latest commit. Should be good.
