We show which devfiles support debug and which support deploy. However, as suggested by Mohit, it might be helpful to provide the option to filter out devfiles which don't provide these options.

I think we could accomplish this by adding checkboxes on the side (bad edit of photo to convey the idea):

@vrubezhny here is another UI-related PR. This one is more involved

An example registry URL is the staging Devfile registry, which hosts the most up to date versions of the default registry's Devfiles: https://registry.stage.devfile.io
