Sort taskProxies in cylc show

It was possible for taskProxies when doing 'cylc show' to be in an odd order:

Task ID: 20240728T0000Z/b
Task ID: 20240727T0000Z/b
Task ID: 20240729T0000Z/b

After this change, they are always sorted by the ID of the task:

Task ID: 20240727T0000Z/b
Task ID: 20240728T0000Z/b
Task ID: 20240729T0000Z/b
