- Two of the linters changed their names
- Updated code and nolint comments to make all linters pass with 1.44.2
- Added a new hack/install-linter.sh script to help developers install
the expected version of the linter for local development
Mainly, avoid using some `testing` helpers that were added in 1.14, as well as a couple of other niceties we can live without.
