Tim/sharepoint trade article

@tmhammer sorry for so much back and forth on this PR.

I opened the URLs generated by this statement and they all gave me a 404 error. By parameterizing the seo_metadata_title you're guessing at what the URL might be. This will typically lead to incorrect URLs being generated, especially when there are significantly more source docs. Is there a more robust way to get this value? It is best to extract it directly from the source, so that there's no guessing involved. I understand that it might not be present there though.

Also, this line is giving me a warning when running specs:
```
[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.
```
Are you also seeing this? Ideally we don't want to see such a warning.
