Sync desktop breakpoints (Breakpoint alignment phase 2)

Continuing the work contained in https://github.com/guardian/frontend/pull/5774, this PR syncs breakpoints above tablet, essentially aligning article breakpoints with those used on fronts.

A final PR will be needed to clean up duplication in the code base resulting from the fact that `leftCol` is now the same as `faciaLeftCol`, `rightCol` the same as `desktop`.
sorry - 119, 131 etc
