Adds newsletter section to site, initial newsletter.

Looks sensible to me

Thanks @twinkarma - plan is not to merge until newsletter content is done.

I should change this to use collections.

Collection based implementation is working nicely.

There is an issue with the navigation bar at certain horizontal resolutions, where it overlaps onto 2 rows rather than folding down to the mobile nav.

Either need to reduce the total number of top level items, or change the breakpoint for navigation compaction.

The easiest solution is probably to just fold newsletter into the RSE Community heading?
The PR to add the uni logo to the navbar would probably exacerbate this (and might need fixing independantly regardless)

Thanks @ptheywood and @twinkarma - maybe worth considering in relation to #257. The whole RSE Community section needs review as well. This may change the headings / organisation thereof.

[bobturneruk]

Community section review now #264

[bobturneruk]

I've added newsletter content.

Maybe worth mentioning that Fariba is part of TUOS ML group.
