refactor(dialog)!: remove deprecated MessageDialogOptions.okLabel (#3612)

* refactor(dialog)!: remove deprecated MessageDialogOptions.okLabel

Use `buttons: { ok: 'label' }` instead. `ConfirmDialogOptions` (used by
`ask` and `confirm`) still accepts `okLabel` and `cancelLabel`.

* Apply suggestion from @amrbashir
