Update start a trial option in top right drop down to include "gold"

Problem

Currently, our trial CTA in the top right dropdown is "Start a trial 🚀" which directs the user into the trial sign up process. However, the user may not know that they are trialing the Gold tier.

Related feedback we've received in the Slack product channel "I don't know what I'm starting a trial of".

Solution

We should update the trial CTA in the top right dropdown to be "start a Gold trial 🚀".
