Idea: Add function that outputs the type of version change

[SaschaMann]

It would be useful to automatically apply labels depending on how the version changes, e.g. major, minor, patch, dev.

To make this easy, a function that either prints this information directly or the old and new version to stdout in a machine-readable format would be required. The labelling itself can be handled in the workflow/CI script.

Sounds like a good idea to me!

I just found out about ::set-output. Printing "::set-output name=master_version::v1.0.0" and "::set-output name=pr_version::v1.1.0", and/or "::set-output name=change_type::{major|minor|patch|dev}" would make it easy to use the output in later steps.

Then one can access it with ${{ steps.<VersionVigilanteStepId>.outputs.change_type }}.
