Pairing issue: Jackson 2.14.x can't serialize on Android < 8 (SDK 26)

ktor-serialization-jackson 2.2.3 depends on jackson-databind 2.14.1. but jackson 2.14 has dropped support for android < 26

upstream ticket: https://youtrack.jetbrains.com/issue/KTOR-5579/Jackson-serialization-is-broken-on-older-Android-devices

downgrading ktor to 2.1.3 would give us a temporary workaround, if needed https://github.com/ktorio/ktor/blob/2.1.3/gradle/libs.versions.toml

forcing a jackson version without downgrading ktor may also work.
