Copiloting dashboard missing organisation info

[Jongmassey]

#3571 changed the relationship between Project and Org to be many-to-many. As part of this, 71f9d15 changed the context data for the Copiloting dashboard view to respect this new relation. However, the template seemingly was not updated and so the organisations field is not displayed.

Correspondingly it's not therefore clear whether the exclusion of uncopiloted organisations (Bennett, Bristol, LSHTM, Graphnet) is properly respected in this dashboard.
