'slide' aria-label attribute added to <a> tags

[bjdevil21]

Our accessibility people came back with this suggestion for screen readers:

"The pager (the dots under the slideshow when there is more than one slide) need labels (or ARIA labels). Currently a screed reader reads them as "List of 4 items. 1 group, 2. 2 group, 3..." etc. in VoiceOver. In JAWS sr says “link clickable 1, link clickable 2" It's not clear to the user what these links refer to.

This is the pager on https://newdesign-new-fitness.ws.asu.edu/:

1. 1
2. 2
3. 3
4. 4

You can either change the link wording:

Slide 1

or add an aria-label:

1

to identify the link."

I didn't update the minified file (build process handles this?)
