Text in "ACA-Py and AnonCreds Workshop Using Traction Sandbox" is unclear

[shearichard]

In docs/demo/ACA-Py-Workshop.md (served at https://aca-py.org/latest/demo/ACA-Py-Workshop/#lab-1-steps-to-follow ) the following text was very difficult to make use of.

If it said ...

Clicking the “BCovrin Test” Action icon (Head and shoulders with plus sign) in the Endorser section

... it would be a lot clearer. I almost gave up because I just couldn't understand what was meant to be done.

I'm happy to do a PR if that is useful.

A PR would be very much appreciated. I vaguely recall that being a bit tricky as well, so if you have any suggestions on a UI improvement, that would be welcome as well.
