Does this PR introduce a user-facing change?

--init-ctr completions now work.

[NO NEW TESTS NEEDED] Since I don't know how to test completions.

@Luap99 Is there any way to test completions?

@Luap99 Is there any way to test completions?

Depends, we test argument completion in test/system/600-completion.bats but this is only for things like image or container names that we know exist. We also test that all options and commands have a completion function set in cmd/podman/shell_completion_test.go

We do not test for simple flag values like this PR implements and I don't see a strong reason to do it.
