Write Better with Vale: Suggestion to include a 'Troubeshooting' section for typical issues

[s2k]

Some programs automatically save YAML files with the extension ‘yaml’, which isn’t recognised by vale (which exclusively uses ‘yml’.

I suggest putting a hint about this potential issue in the book. It took me a good while to realise why a newly created rule wasn’t applied.

While I don’t think a troubleshooting section will be terribly useful, I do think this is an important callout I hadn’t considered, and have added an explicit warning about this in chapter 3 when you create your first rule. Thanks for reporting this.
