Fix content at the bottom of Challenge Details pages

I realized when working on creating a challenge with Kiril that the links at the bottom of the challenge details page that come with every challenge are pointing to the help center, which we are no longer using

Example challenge: https://www.topcoder.com/challenges/30122094

The content should be reviewed, and if we are going to use the same links, please have them link the the Thrive article instead of the Help Center.
