Golang Package Dependency Version

### 📋 Description

As a project template maintainer, I want to present my dependency versions on my GitHub Readme. So people know if I'm using the latest and greatest version of that one truly awesome framework they wanna work with, or if the repo is just dead and unmaintained.

Also, for my use case it must be possible to specify a subfolder in the monorepo

### 🔗 Data

There is already a badge to display the go version. Like npm everything is documented inside the go.mod file which must be parsed and then everything can be read

### 🎤 Motivation

As mentioned, you could use it to display it on your main page to see if dependencies have an older version of a framework and needs to be updated. It can warn users from using way too old versions of frameworks

Start by locating the existing badge that displays the Go version and inspect how badge requests are implemented. Read the target repository's go.mod parsing behavior, including the requested monorepo subfolder case. Done means a badge can display a selected dependency version from go.mod and the behavior is documented.
