Core-107

• Click interaction added to borrower image by wrapping it in a router-link.
  - There's a conditional in place that if allSharesReserved is true, we disable the < router-link > by converting it to a span tag.
• Tracking info added for borrower image click and "Read more" cta button click added based on spec in ticket.

I'd like to get this merged into master branch and then work on the additional changes requested in slack and captured in CORE-110 & CORE-111

The conclusion of that discussion was the following work.

• We will add the “Learn more” text link after the loan use statement,
• When all loan shares are reserved,
  • we will replace the CTA button with the “another lender has selected this loan” message
  • Hide the “Learn more” text link
  • Remove the link from the image (This change is present in this code review)
