Update KAL and GolangCI-Lint to v2

[JoelSpeed]

This updates golangci-lint to v2, and moves KAL to use the Go plugin method that we are using on K/K, and then applies a handful of safe fixes produced by the linter.

The fixes are predominantly adding missing optional tags to fields or removing duplicates or removing required/optional from type declarations where they shouldn't actually exist

We currently don't have 1.24 images, do we?

[everettraven]

Doesn't look like it :).

Do we have an ETA on when we would have them? I'm assuming we will need to have them before the next kube rebase since kube-api-linter should be following the same Go version as upstream kube

Should we add a configuration for the new uniquemarkers linter to prevent duplicate feature-gate markers on fields and types?

[JoelSpeed]

Yes we should, will need to work out what the appropriate configuration is for that 🤔

[everettraven]

Overall LGTM. Only a single comment on potentially configuring the new uniquemarkers linter to enforce uniqueness on some of our custom markers, but that could always be a smaller, focused follow-up if you just want to get this in as-is.
