build: update go-pretty v6 [skip ci]

In this commit we update go-pretty to use the latest v6 version of the
library. The existing version we used had a reported vulnerability.
Updating to this newest version also helped to shrink our set of
indirect dependencies.

In the future we can use
https://github.com/lightningnetwork/lnd/pull/5870 to detect/flag these
issues automatically.

Fixes #6293
