Update collaborator permissions more easily on Overleaf

Today we released a small but hopefully very useful update to the Share modal in the Overleaf editor: project owners can now change their existing collaborators' permissions without having to remove and re-invite them!

We realise that this in itself is just a small change, but we wanted to highlight it as it's part of a wider set of improvements and bugfixes we've been steadily working through to help improve the ease of use of the editor.

More updates to come soon, and if you have any specific feedback on the editor or on your use of Overleaf in general, please do let us know, we'd love to hear from you!
