Adding GOBIN to PATH

[francislavoie]

First, I just wanted to say, huge thanks for this repo/README, it helped me a ton. I've been working on setting up github actions for Caddy.

In your README, you note:

The setup-go action doesn't set PATH, so currently it's not possible to go install a program and run it directly. Until that's fixed, consider absolute paths like $(go env GOPATH)/bin/program.

I just wanted to point out that I figured out that you can just do this on any step after setup-go, pretty much entirely smoothes that issue over:

echo "::add-path::$(go env GOPATH)/bin"

Yeah, I've seen similar magic before, but I initially preferred to stick to documented features :)

We can add it though, since there still isn't an official portable way to do this.

Well, it is documented: https://help.github.com/en/actions/reference/workflow-commands-for-github-actions#adding-a-system-path and it works on all shells, not just bash.

Thanks for adding it to the README!

Ah, my bad! It wasn't documented when I last looked :)
