Rename "Feature" to "Features" in test folder

Should be plural. No idea why it's singular.

@driesvints Why should it be plural? All I see in the community is the folders with a singular name

@MichaelDeBoey you're right! No idea why I thought it would be different.

Just looked at the issues I could maybe help with and found this one a bit odd that's why I was asking, just to be sure 🙂

Saw you also changed it for the rewrite of the portal (laravelio/laravel.io#241) 🙂
Keeping small things like this consistent through the whole community is something I see more when browsing more through interesting project 🙂
