[bushrat011899]

Objective

• Fixes Add Commands::run_schedule #16495

Solution

• Added Commands::run_schedule, which internally calls World::try_run_schedule, logging any issues.

Testing

• Added doctest
• Ran CI

Showcase

Instead of writing:

commands.queue(|world: &mut World| world.run_schedule(FooSchedule));

You can now write:

commands.run_schedule(FooSchedule);
