feat(minecraft/scheduler): add isCancelled and getTaskId methods to S…

…chedulerTask interface and implementations

This commit adds two new methods to the SchedulerTask interface and its
implementations: MinecraftFoliaScheduler and MinecraftBukkitScheduler.
The isCancelled method returns true if the task has been cancelled, and
the getTaskId method returns the unique id of the task.
FoliaMC does not provide a task id.
