finatra, scrooge, finagle: Update malformated changelog entries

Problem

When doing the release, we found a couple malformed entries,
in addition to an entry that shouldn't be there at all.

Also, our release docs don't mention that we need the TSS
CLI tool.

Solution

Update the changelog entries and update our release docs.
