Migrate to Jakarta APIs

[boris-petrov]

Jakarta EE 9 is out already along with stable versions of the two most popular containers - Tomcat 10 and Jetty 11. shiro-jersey internally still uses javax (e.g. import javax.ws.rs.core.Response in ShiroExceptionMapper) so it is incompatible with an application that runs on these two containers. It would be nice to release a new version that is compatible with them. Unfortunately a single version cannot be made compatible with both the "old" javax and the "new" jakarta namespaces so perhaps a new major version should be released.

The migration is simple enough - just depend on the new artifact versions and rename the imports from javax.* to jakarta.*.
