Update go tool dependencies, restructure lint targets (#24239)

- Update all tool dependencies to latest tag
- Remove unused errcheck, it is part of golangci-lint
- Include main.go in air
- Enable wastedassign again now that it's
[generics-compatible](https://github.com/golangci/golangci-lint/pull/3689)
- Restructured lint targets to new `lint-*` namespace
