Create a hook for validating file name

💡 **Idea**

When it comes to documentation, the usage of lowercase and hyphens in files names is important. This is because the name of the files set the final slug in the URL of the docs.

It is likely that a developer uses snake case or camel case when creating a source code file. However, these naming conventions should be avoided for files that render into docs.

Thus, I am proposing the creation of a hook that ensures a file is compliant with a certain naming convention.
