Package org.infinispan.context is missing from javadocs of 10.1.x and 11 releases

The new release of the custom infinispan doclet fixes the handling of @private/@public javadoc tags which are very strict now. Packages that are not specifically annotated are excluded, as it was meant to be from the beginning, but the exclusion was slightly broken.

We need to add `@public` to all packages that we find to be unintentionally left out.
