mcp-json-jackson2 (and jackson3) don't have a export package (like mcp-core)

[jcompagner]

if you look at mcp core:

https://github.com/modelcontextprotocol/java-sdk/blob/main/mcp-core/pom.xml#L44

there you see export package
but that is missing from the

https://github.com/modelcontextprotocol/java-sdk/blob/main/mcp-json-jackson2/pom.xml#L42
and also from the jackson3:

https://github.com/modelcontextprotocol/java-sdk/blob/main/mcp-json-jackson3/pom.xml#L42

could this be added? because now those 2 jars are not usable in a osgi because you can't use any package from it.
