Remove link to training survey

[maneesha]

On the Wrapping up lesson, we link to the post-training survey. However, if trainees use this link, we can not match up their responses to the training they attended. I recommend removing the link to the training survey and direct trainees to use the link they were provided specifically for that training.

Also, call it a post-training survey as we use the term "workshop" specifically to refer to our DC/LC/SWC workshops.
