remove two deprecated unused functions

[Luap99]

pkg/util: remove StringInSlice()

It is not used by other tools anymore and callers should just use
slices.Contains() now.

---

pkg/config: remove ValidatePullPolicy()

It was deprecated and beside on caller here it doesn't seem to be used
by podman/buildah so just drop it.

Also ParsePullPolicy() already does strings.ToLower() on the input so
there is no need for the caller to do that again.

Summary by Sourcery

Remove two deprecated and unused functions and update callers to use the recommended alternatives

Enhancements:

• Remove deprecated util.StringInSlice and drop its slices import
• Remove deprecated config.ValidatePullPolicy and simplify pull policy validation to call ParsePullPolicy directly
