Templates: direct updating of collaboration templates

[techsmyth]

Description

As a support user or space admin I want to be able to directly update the collaboration flow in subspace templates templates

Acceptance criteria

• [ ] Allow editing of collaboration entity in Collaboration Template directly in the Template entity, using the UX controls like are there on a subspace
• [ ] ...

TBD: work involved in making the collaboration entity directly updateable on client? TBD: events that get emitted server side?

Additional Context

The current route is to a) create a subspace from a collaboration template b) edit the collaboration flow including callouts on the subspace c) save the collaboration flow as a collaboration template

Areas that will be affected

To be added during the refinement
