Add 'go-version' Output (#85)
* Add go-version to action outputs

This provides the semver version of Go that has been installed. This is useful
if only a major or minor version has been provided as the input go-version
value.

* Convert version extraction to a function

Simplify how the version is extracted and add a simple test at the same
time.
