Secret Handshake exercise should have `Signal` class/enum visible/editable

For the online editor, it's not clear that the enum is already defined, so students might attempt to redefine it inside HandshakeCalculator. That causes deceiving compilation errors.

Thanks for pointing this out.

The fix here is to add a files.editor key in exercises/practice/secret-handshake/.meta/config.json containing that extra file - this will make the editor aware of that file and show it in reading mode.

https://github.com/exercism/java/pull/2191 @andrerfcsantos is there any way I can test this change before merging?

@artamonovkirill Unfortunately, no. I left a comment on the PR.

Thanks for doing this. I noticed this is a problem in a lot of other exercises too - they have extra files but are not declared in either the files.solution or files.editor key (#2170). I've meaning to write a little script to fix instances where this happens, but haven't find the time yet. In the meantime, feel free to create PRs about this for the exercises you are solving.

@andrerfcsantos I wrote the script to check exercise files and added missing files: https://github.com/exercism/java/pull/2195 😁
