Typo in the documentation.

I'd like to point out a mismatch with the online documentation about the parameter on the hierarchy of requirement types:

serenity.requirements.types doesn't work, I had to use instead serenity.requirement.types (without s for requirements)

Can you propose a PR - you can use the "Edit this page" button at the bottom to propose a fix.

Well done!
