@okwasniewski this targets this, correct? (just trying to link them in gh)

• [0.74.4]ERROR: [ContentDelivery.Uploader] Asset validation failed (90360) Missing Info.plist value. A value for the key 'MinimumOSVersion' in bundle XXXX.XXXX/Frameworks/hermes.framework is required. #45823

Not really, this is a PR with additional fixes that will prevent this happening in the future, we are working together with @cipolleschi here: #45840
