Add helpful instructions/labels for the Beanstalk auth form.
Review Request #10068 — Created July 5, 2018 and submitted
Beanstalk no longer allows users to authenticate using their standard
password, instead requiring an access token. This change updates the
Beanstalk auth form to describe the authentication requirements and to
change the label to "Access token."
Went through the repository configuration process and saw the new
instructions and text.
