Add support for Appraisal

[hlascelles]

If a ruby project is using Appraisal, it would be convenient if the necessary lock files were updated.

Essentially, this would involve calling bundle exec appraisal install. An example would have been this PR that would have resulted in 3 files being changed.

I'm not sure if you would see this as a thin end of the wedge to adding a whole load of build tool chains?

Thanks for this @hlascelles, and sorry for the slow reply.

I'd really like to support Appraisal. I need to look into exactly what happens when appraisal install is called, but can see us working something out here.

Wonderful. Thanks very much!

Still valid.

Closing this as we don't think we'll support it directly in Dependabot. You could do this with an Action that runs on Dependabot PRs.
