useArtifacts should support setValue/dismiss/etc by ID instead of by type

[barbinbrad]

If we have multiple artifacts of the same type, it is impossible to set the current artifact to be a specific artifact. A better API for actions might be:

interface UseArtifactsActions {
    setValue: (value: string | null) => void;
    dismiss: (type: string) => void;
    restore: (type: string) => void;
    setValueById: (id: string | null) => void;
    dismissById: (id: string) => void;
}
