Support Golang v1.18

[timo-klarshift]

Go v1.18 has been released and after upgrading some projects to that new version code-climate fails:

type Event[T any] struct {
	Time    time.Time
	Service *Service
	Message string
	Body    T
}

error: (CC::CLI::Analyze::EngineFailure) engine golint failed with status 1 and stderr 
Could not lint file: /code/pkg/service/event.go
Error /code/pkg/service/event.go:8:14: expected ']', found any (and 3 more errors)

Here the particular reason is the generic part [T any] which is new in golang 1.18
