Joel Marcey 01ebbb1512 Check for required folders based upon headerLinks right up front (#111)
I was getting this error when running the examples:

```
Error: It looks like you've enabled language support, but haven't provided translated files. The document with id: 'en-doc1' doesn't exist.
```

However, this error was an indirect result of me not renaming the `docs-examples-from-docusaurus` directory to `docs` since I had `doc` in my
`headerLinks` in the example siteConfig.js.

So let's check the headerLinks and make sure we have the required directories.

Here is an example of the error if I try to load a Docusaurus site just after running `npm run examples` without having renamed the directories.

```
Error: You have 'doc' in your headerLinks, but no 'docs' folder exists one level up from 'website' folder. Are you running the examples? If so, make sure you rename 'docs-examples-from-docusaurus' to 'docs'.
