README.md suggests to install a package without version info:

```sh
$ go install github.com/asticode/go-astilectron-bundler/astilectron-bundler
go: 'go install' requires a version when current directory is not in a module
	Try 'go install github.com/asticode/go-astilectron-bundler/astilectron-bundler@latest' to install the latest version
```

This update adds `@latest` as the message suggests.
