Lint is failing with some inscrutable panic (on a commit with no code changes). Let's try bumping the version in case they fixed it. Additionally, the new version's github action uses Go 1.19, which means it pulls in gofmt updates to match the new [doc-comment formatting rules][1]. So I added Go 1.19 to our list of versions to test (fixes #216) and updated some of our doc-comments to format better in the new world (mostly using the new link syntax).
