Remove replace directives from go.mod

[anuraaga]

Is your feature request related to a problem? Please describe.

Currently, because the go.mod has replace directives, this project cannot be go installed or go runed. While it's not uncommon for projects to expect using precompiled binaries, I think it is still a reduced developer experience. Notably, orchestrion does not have this issue so if comparing UX with that project and wanting to "win", then this could be something worth fixing.

Describe the solution you'd like

Remove replace directives from go.mod, likely introducing a go.work instead.

By the way, I see github.com/alibaba/opentelemetry-go-auto-instrumentation/test/verifier in my go.mod anyways so it seems like separating the modules doesn't cut down on the dependencies in the instrumented app currently.
