`npm run docs` doesn't work on Windows

```
C:\Users\xmr\Desktop\cli>npm run docs

> netlify-cli@8.6.12 docs
> node ./site/scripts/docs.js

Docs updated!
No files matched pattern [
  'C:\\Users\\xmr\\Desktop\\cli\\README.md',
  'C:\\Users\\xmr\\Desktop\\cli\\docs\\**\\**.md'
]
```

I suspect it's due to the backslashes.
