Post-send screen CTA needs copy improvement

### What is this about?

As a user, when I complete a send transaction, I get a confirmation screen with 2 CTAs on it. The copy on the CTAs doesn’t make grammatical sense and could be improved. Specifically "create new send" as an option. This should be revised.

Start by locating the post-send confirmation screen in the mobile app and search for the CTA text "create new send." Update the CTA wording so it is grammatical, then verify the confirmation screen displays the revised copy alongside the other CTA.
