This is because all your code is under the docs directory which is commonly used for… documentation 😁 so Linguist ignores it and everything within it:

https://github.com/github/linguist/blob/d7799da826e01acdb8f84694d33116dccaabe9c2/lib/linguist/documentation.yml#L12

You can implement an override to tell Linguist to not consider the directory as documentation.
