    coroutines: Allow parameter packs in co_await/yield expressions [PR95345]

    This corrects a pasto, where I copied the constraint on bare
    parameter packs from the co_return to co_yield/await without
    properly reviewing it.

    gcc/cp/ChangeLog:

            PR c++/95345
            * coroutines.cc (finish_co_await_expr): Revise to allow for
            parameter packs.
            (finish_co_yield_expr): Likewise.

    gcc/testsuite/ChangeLog:

            * g++.dg/coroutines/pr95345.C: New test.
