Test Plan

1. Run "sg start dotcom"
2. Navigate to "https://sourcegraph.test:3443/cody/subscription"
3. Check Pro card using inspection
4. To check second case, head to client/web/src/cody/subscription/CodySubscriptionPage and on line 206 refactor isProUser to `!isProUser

The solution looks right but the Loom talks about and displays top margin while the change involves setting the bottom margin (of which, the latter is the idiomatic solution). This feels contradictory (maybe the Loom was done with a different change on the code?), but approving the PR because the change looks right.

Hi @vdavid I forgot to remove the loom video after the app failed to run locally. I will ensure to update everything else going forward. Here is loom video
Thank you
