`!mjolnir rooms` should show room name next to the Room ID

**Is your feature request related to a problem? Please describe.**
When you have lots of protected rooms, the long list of only room IDs returned by `!mjolnir rooms` isn't very helpful

**Describe the solution you'd like**
Show the room name and possibly other helpful info like for example topic or canonical alias next to the room ID

**Describe alternatives you've considered**
None comes to mind

**Additional context**
None

Start by locating the implementation of the `!mjolnir rooms` command and inspect how it currently retrieves and formats protected room IDs. The change is done when the listing shows each room name next to its Room ID, with any additional metadata limited to what the command can reliably obtain.
