Notes

• This PR adds the campaign_id in the action_data field for campaign button events.

Test Steps

1. Change device region to Japan and device date to May 29th.
2. Launch app on Staging. Background app on Explore feed. Foreground, then pull to refresh to fetch campaigns.
3. Visit an article. Tap the Close button on campaign modal and confirm you see campaign_id listed out in the console for button tap event.
4. Repeat steps 2-3 for other campaign modal buttons (donate, maybe later, I already donated), confirm campaign_id is now sent with event.
