springbootdemo: Gemini review fixes — uri.endsWith consistency and axis2.version property use

- Replace uri.contains(\"/swagger-ui\") with uri.endsWith(\"/swagger-ui\") ||
  uri.contains(\"/swagger-ui/\") in OpenApiServlet (both springbootdemo and
  springbootdemo-tomcat11) — prevents false matches on URIs that happen to
  contain /swagger-ui as a non-terminal substring
- Use \${axis2.version} property for axis2-openapi dependency version in
  springbootdemo-tomcat11 pom.xml — consistent with the property already
  used in the antrun copy tasks added in the previous commit
