ci: enable more golangci-lint checkers, update config for Go 1.18

Commit 3f5cb13 updated CI for Go 1.18
as well as the version of golangci-lint. However, it omitted updating
the golangci-lint configuration to default for Go 1.18 instead of Go
1.17. This commit does this and also enables more checkers.
