Update G-Cloud labels as per Raphaelle's request

It's much easier to get the customer sector now, so "not yet classified"

that we don't have a clean category for yet, so "Unknown" is now more
appropriate than "Not yet classified".
Remove 'not yet classified' from SME/Large

There should no longer any rows which have an unclassified SME or Large
column, so this axis will always be zero.
