Use rememberUpdatedState to prevent stale lambda capture

If a composable passes a lambda argument down to other composables via wrapping, lambda gets captured which may not read the latest state when executed. rememberUpdatedState fixes this problem.

Hi, @halilozercan thanks for this fix. Could you please also add it to the HarmonyColorPicker composable, to keep both in sync

@halilozercan thanks for spotting this - i've made a change in #30 for both pickers
