Resolve execution issues after Struts2 7.0.x migration (#442)

1. Added struts.allowlist.packageNames configuration

2. Modified Jetty 12 Maven Plugin configuration for EE10

3. Downgraded JasperReports version to 6.x
the example's our_jasper_template.jrxml is not currently compatible with the JasperReports 7.x format.

4. Updated web.xml to Jakarta EE 10 namespace and Servlet 6.0 schema

5. Fixed minor typos
