Transactions Explorer to Performance Platform

Many of these links aren't actually served by Transactions Explorer,
and any that still are won't be in the coming weeks or months.

It doesn't make sense to label things as being from the Transactions
Explorer when that's not a thing that will exist for a lot longer.
