Subject: [PATCH] Pinned Ghost + Tinybird Sync container to same image

Closes https://linear.app/ghost/issue/ENG-2414

- These two containers must run the same version of Ghost since the TB container uses assets from the Ghost container
- If the two are out of sync we'd be updating or migrating Tinybird to a different set of APIs than what Ghost is expecting which could break things
