Revise grammar of organisation closed page

Does it close up? Or sideways? I make this pull request because the two most important pieces of information are Org Name, and whether it's closed or not....and my eye gets confused by the word "down".

Reference GOV.UK [content guidance](https://www.gov.uk/design-principles/style-guide/writing-for-the-web)....or TL;DR, shorter and to the pointer is gooder.
