🤖 Add stub files to all exercises

[ErikSchierboom]

In this PR, we created (empty) stub files for all exercises that didn't yet have them.

The lack of stub file generates an unnecessary pain point within Exercism, contributing a significant proportion of support requests, making things more complex for our students, and hindering our ability to automatically run test-suites and provide automated analysis of solutions.

The original discussion for this is at exercism/discussions#238.

Closes #319

We will automatically merge this PR in two week's time if it has not been merged by track maintainers at that point 🙂

This is likely going to conflict with #249 and #410. Once the pull request is merged most of the exercises should have stub files in place.

[ErikSchierboom]

@m-dango Well, it's not only that the stub files have to be in place, but also that the paths in the exercises' .meta/config.json file should be correct. Is there any harm/danger in merging this PR first?

[m-dango]

Many of the filenames will change as the generator creates them to match the file patterns in config.json. e.g. The changes in exercises/practice/secret-handshake/.meta/config.json for example will need to be undone.

Looking a bit closer, it seems that something has gone wrong with the secret-handshake changes. It looks like the solution file has been moved and the test is no longer able to find it, its expecting a SecretHandshake.pm file.

Ah okay. I would then suggest to close this PR and wait for the other PRs to fix the issue of missing stubs. Agreed?

[ErikSchierboom]

@m-dango Do you perhaps have any idea when #249 will be done? I'm asking as adding the stubs to perl5 is on my v3 launch to-do list :)

@ErikSchierboom I'm moving house roughly in the next couple weeks so I'm not too sure unfortunately. There is currently an outstanding PR for one of the exercises here (#417), and I'd be fine with pausing it from that point, adding the outstanding stubs for the remaining exercises separately, then putting them on the generator later, if that helps things move along.

That should mean there are currently only up to 12 exercises that might not already have stubs.

I like that suggestion.

@m-dango I've rebased on the latest main and fixed the missing stub files and invalid file paths in this PR.

configlet now only complains about an empty tags array:

~/exercism/perl5$ ../configlet/configlet lint

The `tags` array is empty:
