fix(java): avoid unexpected initialization of JacksonParser in Graal 22.2

[mpeddada1]

Running storage tests in GraalVM 22.2.0 results in:

Error: Classes that should be initialized at run time got initialized during image building:
com.fasterxml.jackson.core.JsonToken was unintentionally initialized at build time. com.google.api.client.json.jackson2.JacksonParser$1 caused initialization of this class with the following trace: 
	at com.fasterxml.jackson.core.JsonToken.<clinit>(JsonToken.java:31)
	at com.google.api.client.json.jackson2.JacksonParser$1.<clinit>(JacksonParser.java:121)

The root cause was the specification of com.google.api.client.json where we were initializing the whole package at build time. This PR initializes only the necessary classes at build time to resolve this.
