Can't build _examples/http since v0.20.0

[kei2100]

Summary

Since Scope.SetTransaction() was removed in issue #605, building the _examples/http now fails.

Steps To Reproduce

$ git clone https://github.com/getsentry/sentry-go
$ cd sentry-go
$ git checkout refs/tags/v0.20.0
$ cd _examples/http/
$ go build
# github.com/getsentry/sentry-go/_examples/http
./main.go:109:15: hub.Scope().SetTransaction undefined (type *sentry.Scope has no field or method SetTransaction)

Thanks for letting us know about this. Fixed in #621 🙂
