Update golangci-lint to v2.0.2

[belimawr]

elastic/beats#42026 Is updating the GitHub Actions and lint configuration (.golangci.yml) to V2. Because we need a total of 3 PRs to get all changes into Beats, there will be a brief period when running mage llc on Beats will fail due to the version miss-match.

What does this PR do?

See title

Why is it important?

It fixes some issues we're seeing in Beats, e.g:

filebeat/input/filestream/input_test.go:25:2: could not import sync/atomic (-: could not load export data: internal error in importing "sync/atomic" (unsupported version: 2); please report an issue) (typecheck)
        "sync/atomic"
        ^

Folks, I finished updating all configuration files. It's ready for review again.

LGTM, I don't see anything obviously wrong with the config.
