Add Javadoc for wallet-core-proto and wallet-core-kotlin-jvm

[EmanuelLoos]

Is your feature request related to a problem? Please describe.
In order for apps using wallet-core to be included in F-Droid, wallet-core needs to be published to a maven repository which F-Droid trusts, one option being mavenCentral. I did some testing using the artifacts from GitHub and found that the Javadoc for wallet-core-proto and wallet-core-kotlin-jvm is required by mavenCentral, but missing.

Describe the solution you'd like
Please include Javadocs in the maven build artifacts of wallet-core-proto and wallet-core-kotlin-jvm.

Describe alternatives you've considered
None.
