This PR fixes an issue I've run into on the RAS-ACC testing site, but that I can't recreate locally 😕

When using reCAPTCHA 2, either after successfully passing the reCAPTCHA by picking bikes/crosswalks/traffic lights, or after getting an error, the registration modal has a side-scroll due to the recaptcha badge:

How to test the changes in this Pull Request:

1. Set the site to use the invisible flavour of reCAPTCHA 2 under Newspack > Connections.
2. In an incognito window, try signing in; hopefully you're like me and your behaviour is spammy enough to trigger something.
3. After picking your bikes successfully and getting to the success screen, or getting an error on the initial screen, scroll the mouse to the right -- hopefully you get this:

4. Apply the PR and run npm run build.
5. If you do get the side scroll, confirm that the PR fixes it; otherwise, please confirm that it doesn't cause any weirdness. The issue is the right style, but locally I only get three lines of inline CSS for this badge vs. ~12 for the RAS-ACC test site.
