🤖 Add file patterns to config.json

[ErikSchierboom]

⚠ This PR requires you to make a simple change before merging. ⚠

---

To save maintainers from having to manually specify the files key in their exercises' .meta/config.json files, we are providing support for track-level patterns. See this PR for details.

This PR adds (purposefully wrong) file patterns to the config.json file. It is up to you, the track maintainers, to change these patterns to their correct value.

You can use the following placeholders:

• %{kebab_slug}: the kebab-case exercise slug (e.g. bit-manipulation)
• %{snake_slug}: the snake_case exercise slug (e.g. bit_manipulation)
• %{camel_slug}: the camelCase exercise slug (e.g. bitManipulation)
• %{pascal_slug}: the PascalCase exercise slug (e.g. BitManipulation)

We will soon update configlet to enable it to automatically populate the .meta/config.json file's files property, at which point we will then batch-PR updates to all tracks that have merged this PR.

@leobenkel This PR actually requires a change to be made :)

@leobenkel I'm sorry I wasn't clear, but what I meant was that this PR is not ready to be merged as its contents should be modified by maintainers first :)

Oh I understand. I think Github has a feature to mark PR as draft, that could avoid confusion :)

[ErikSchierboom]

Ah yes, that would have been useful. Sorry!

I'm not sure this is what it's required here, but in general, as far as scala with sbt is concerned, you have src/main/scala for the app files and src/test/scala for the tests. there is a scala part because there could be also a java folder there, and main, test are environments-level, so there could be a staging or production there.
