fix: segmented reactions on press

[isekovanic]

🎯 Goal

This PR addresses a behavioural change that unfortunately slipped through with V9 that diverges from what we had in the previous versions. Namely, for segmented reactions we applied reaction toggling instead of targeted opening of the reaction info bottom sheet.

This diverged from the other SDKs and so here we align this divergence.

Additionally, we pass reactionType to additionalInfo and make sure it's propagated everywhere so that we can easily replicate the behaviour if needed, like so:

<Channel
  onPressMessage={({ emitter, additionalInfo, actionHandlers, defaultHandler }) => {
    if (emitter === 'reactionList' && additionalInfo?.reactionType) {
      actionHandlers?.toggleReaction(additionalInfo.reactionType as string);
      return;
    }
    defaultHandler?.();
  }}
/>
