type: fix broken types in dependencies

aiosignal 1.4.0 has been released including feature aio-libs/aiosignal#699
However, aiohttp still uses old types which were not merged as well as
were not even implemented (the closest is
aio-libs/aiohttp#11160 and related issue
aio-libs/aiohttp#11036, whoever it still
doesn't change signatures for _AppSignal)

Let's just mark those calls as ignore
