What to do

1. Open the docs page and compare each screenshot against the current Sentry UI
2. For screenshots: recapture from the current UI and replace the image file
3. For Arcades: re-record the interactive walkthrough and update the embed URL
4. Ensure alt text is still accurate for any replaced images
5. Commit and open a PR
