zeta: Add adjustments to the review modal UI (#21920)

Most notably, adding a current iteration of a possible logo to feel it
out! :) Also, I'm hiding the input and instructions container after the
review has been sent. In the future, if we allow changing an already
sent review, we can change this behavior.
