Set KOTLIN_HOME

[jayvdb]

It would be helpful if this action also set KOTLIN_HOME to the appropriate path.

I've run into several cases where tools require it to be set, or require a cli arg provided with this value. c.f. https://github.com/scijava/jgo/issues/89

Hi @jayvdb

thanks for the suggestion. So far I've never encountered KOTLIN_HOME (sounds a lot like JAVA_HOME).

I'd be happy to have the action do this, but I'm not sure when I'll be doing it. Would you be able to provide a PR for the feature, or a failing test to verify it works when implemented?

Just out of curiosity, can you tell me what you're using this action for? Since kotlin is preinstalled on GitHub's runners now, the use-cases for this action became quite narrow and I don't really use it myself, so I'm not putting that much effort into maintenance as also I don't know of many "productive" users.

Happy new year (in :australia: at least :sweat_smile:)
