Hi @alt-shreya,
This is a great start, thank you for the screenshots in the PR description!
The tests are failing because the snapshots are now outdated. You need to update the snapshots, here are the instructions on how to do that: https://docs.openverse.org/frontend/guides/test.html#updating-snapshots

Comment here if you need any help, I'll be happy to do so or to update the snapshots for you if needed.

@alt-shreya, I am going to draft this PR while the changes are being made to prevent Openverse bot from pinging for reviews. Please undraft it when you add the snapshots.

@obulat I've updated the snapshots in my most recent commits. I only updated for visual-regression as these were the tests that were failing. Please let me know if you have more feedback!

Looks great, thanks for the contribution! 😄 One nit for a newline that doesn't appear necessary.
