chore: Remove usages of github.com/pkg/errors dependency (archived)

[zak-pawel]

github.com/pkg/errors has been deprecated and archived: pkg/errors#245

I don't think we still need to use it after all error wrapping done in #12701 #12702 #12704 #12723 #12731 #12733 #12772 and enabling errorlint for guarding it in #12785.

It needs to still be our indirect dependency and cannot be removed from LICENSE_OF_DEPENDENCIES.md because docker still uses it:

go mod why github.com/pkg/errors

# github.com/pkg/errors
github.com/influxdata/telegraf/plugins/inputs/docker
github.com/docker/docker/api/types/filters
github.com/pkg/errors
