Remove archived group

[neil]

Splitting this off into a separate issue so it doesn’t get lost:

@Janet

There is also this other “archived” group, also appearing on the site - would definitely like to get rid of that https://therestartproject.org/groups/transition-town-marlow/

This group has been removed.

For reference, logged an issue in github for deleting groups from the interface.

Thanks!

Ability to delete groups
