Comment:
adding this adds `--version` to the act binary (it was very nicely documented, I only found it by looking at the [arch pkgbuild](https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=act)):
```bash
go_ldflags="-X main.version=${version}"
```

Would it be good to depend on docker? It may allow for other container backends in the future, but currently it's only docker (https://github.com/nektos/act/issues/303)
