Current Behavior

TL;DR: There's been an ask to run linting on all changed files regardless of wether they have been staged using the Makefile. It's proving slightly more complex than anticipated so I'm spinning this into an additional ticket.

See https://github.com/dbt-labs/dbt-core/pull/4639/files/8d900e916e943463d85d9220717b1eacd0e9b764#r803883007
