Update text/URL in Terms and Conditions window for Bisq Price Indices

Since this is a legal agreement, the goal is to limit the liability of
the facilitators of the service, not to explain how we calculate the
price indicies - users can find that information on the "about" page.

Also updates URL for Dispute Resolution to the new wiki article.

Fixes bisq-network#4571
