cli/command/container: fix use of generics

This was introduced in dad1d36, which
did not add a `//go:build` constraint to enable the use of generics (`any`).

Which causes an error when used;

 could not import github.com/docker/cli/cli/command/container (-: # github.com/docker/cli/cli/command/container
 /Users/thajeztah/go/pkg/mod/github.com/docker/[email protected]+incompatible/cli/command/container/stats.go:148:39: predeclared any requires go1.18 or later (-lang was set to go1.16; check go.mod)
