fix: drop containerd v1 dep to resolve govulncheck CVEs

containerd v1 is EOL and will never receive fixes for
GO-2026-5622, GO-2026-5338, GO-2026-5064. The only import
was for `remotes.Resolver` in the deprecated `ClientOptResolver`
stub. Changing its parameter type to `any` preserves the public
API while removing the vulnerable dependency entirely.

It should help for PR like https://github.com/helm/helm/pull/32297
