If the return value from `yield` is inspected inline, such as by (augmented) assignment, changing the looped `yield` to `yield from` is very likely to change the semantics of the generator, since there is an implicit use of `generator.send`. Closes pylint-dev#9696

Description
If the return value from
yieldis inspected inline, such as by (augmented) assignment, changing the loopedyieldtoyield fromis very likely to change the semantics of the generator, since there is an implicit use ofgenerator.send.The type-hint component of #9696 feels (to me) like it would be suitable to suppress with a local lint suppression rather than complex type inference within pylint; it's a pretty unusual construction.
