Functionally works great!

A few styling and minor functional feedback:

1. The mobile layout and spacing don't seem to match the design:

2. The disclaimer should be localized and stored with the select options instead of depending on the google translate so that it shows up in the native language before user clicks on the "Translate" button.

3. The above-mentioned options should be formatted as "French - Français"

Found another issue - the focus is not trapped within the modal when it's open

I believe I've fixed most of the things we discussed, as well as a couple of other issues I ran into afterwards in Mayflower --> massgov/mayflower#2055 (comment)

Please update the openmass PR and make sure that we have:

• All language options in the new list match what's in prod
• The disclaimer should be localized and stored with the select options instead of depending on Google Translate so that it shows up in the native language before the user clicks on the "Translate" button.
