Sort Rooms in a Space by member count

### Your use case

#### What would you like to do?

Sort Rooms in a Space by member count.

#### Why would you like to do it?

Some Spaces, like Debian, are huge and have so many Rooms. I want to know which ones are most used.

#### How would you like to achieve it?

A toggle under a three-dots menu would be nice.

### Have you considered any alternatives?

Manually scrolling through the list. This is infeasible because it keeps loading whenever I go through the short list of new items.

### Additional context

I am using Element (Desktop) on ARM macOS.
