[Bug]: 5.7.x fails builds with R8/Proguard #2576

What happened?

We get the following build failure with release builds (Proguard/R8) when updating to 5.7.x (including 5.7.2):

Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in ...\missing_rules.txt.
Missing class com.fasterxml.jackson.core.JsonFactory (referenced from: com.fasterxml.jackson.core.JsonFactory io.opentelemetry.exporter.internal.marshal.JsonSerializer.JSON_FACTORY and 2 other contexts)

The workaround (according to AI) is to add these to your local proguardr-rules.pro:

# OpenTelemetry - Jackson is an optional dependency not included on Android
 -dontwarn com.fasterxml.jackson.core.JsonFactory
 -dontwarn com.fasterxml.jackson.core.JsonGenerator

But it seems like the library should include any needed rules in its consumer-rules.pro

Steps to reproduce?

Update from 5.6.2 to 5.7.2
Your build now fails.

What did you expect to happen?

I expected to be able to build my app. without hunting down proguard rules to add. as a workaround.
