Replace GetSleepAnimationId with GetIdleAnimationId

[Frostbyte0x70]

Better documents GetSleepAnimationId, which is actually used to get the animation a monster should play while idling. The function has been renamed to GetIdleAnimationId.

Also documents ChangeMonsterAnimation.

Looks fine to me, will wait a day before merging since there's a symbol name being removed.

Oh well I guess an alias is okay too. I figured you didn't want to add one since it's not exactly correct, but I don't mind either way.

I just added the old name as an alias (I forgot the alias system is a thing now), although I don't know if it would be better to remove it, since the old name is incorrect.

I kind of doubt many people use this symbol? So if I had to choose I might lean towards no alias, but will defer to you.

Alright, I'll remove it then. I thought it was mandatory to add an alias since the checks were failing.

It'll only fail for the PR the change is introduced in. So it's an ignorable error.
