Pass linting checks

[ErikSchierboom]

This issue is part of the migration to v3. You can read full details about the various changes here.

The configlet tool has a lint command that checks if a track's configuration files are properly structured - both syntactically and semantically. Misconfigured tracks may not sync correctly, may look wrong on the website, or may present a suboptimal user experience, so configlet's guards play an important part in maintaining the integrity of Exercism.

We're updating configlet to work with v3 tracks, which have a different set of requirements than v2 tracks.

The full list of rules that will be checked by the linter can be found in this spec.

⚠ Note that only a subset of the linting rules has been implemented at this moment. This means that while your track may be passing the checks at this moment, it might fail later. We thus strongly suggest you keep this issue open until we let you know otherwise.

Goal

Ensure that the track passes all the (v3 track) checks defined in configlet lint.

To help verify that the track passes all the linting rules, the v3 preparation PR has added a GitHub Actions workflow that automatically runs configlet lint.

It is also possible to run configlet lint locally by running the ./bin/fetch-configlet (or ./bin/fetch-configlet.ps1) script to download a local copy of the configlet binary. Once downloaded, you can then do ./bin/configlet lint to run the linting on your own machine.

⚠ The original issue did not explain that currently only a subset of the linting rules have been implemented. This means that while your track may be passing the checks at this moment, it might fail later. We (the Exercism team) thus strongly suggest you keep this issue open until we let you know otherwise. The issue's text has been updated to reflect this.

Just a note I enabled the Configlet CI workflow, I think I was the one that disabled it in the spring of 2021 because it was failing and preventing PRs from passing CI checks. There wasn't an obvious issue.

I enabled it just a few minutes ago to see if I could reproduce the error, but everything passed. So I am leaving the Configlet CI workflow enabled.

@ErikSchierboom and @kytrinyx I am closing this since the Configlet workflow is using the configlet action in exercism/github-actions, which does run configlet lint.

Please correct me if there is still work to be done.
