Code that annotates the return values of add_argument_group() and add_mutually_exclusive_group() has to import the private _ArgumentGroup and _MutuallyExclusiveGroup today. Public names give that code a supported type, and the old names stay as aliases so existing imports keep working.

Following @savannahostrowski's suggestion on the issue, this makes
ArgumentGroupandMutuallyExclusiveGrouppublic and keeps_ArgumentGroupand_MutuallyExclusiveGroupas aliases, since existing code imports them.The docs cover what they already promised: the objects that
add_argument_group()andadd_mutually_exclusive_group()return, and theiradd_argument()andadd_mutually_exclusive_group()methods. The constructors stay implementation details.This replaces the protocol approach from #150597.
