chore(deps): Upgrade golangci-lint (#141)

* chore(deps): Upgrade golangci-lint

Also, the documentation recommends running it separately from
other jobs so that they run in parallel.  The main reason I'm
doing that here is because there are a lot of warnings in the
logs that I think are because it is expecting to start with
a clean working environment, which is not the case when it
runs after our other checks.

* chore(dependencies): Use v2 of the golanglint-ci action

* chore(deps): Upgrade setup-go
