build(ucp-observability): configure compiler and javadoc plugins for Java 11

The root pom's javac-release profile forces --release 8 for all modules.
This module uses jdk.jfr which requires Java 11+, so both plugins need
an explicit override:
  - maven-compiler-plugin: <release>11</release>
  - maven-javadoc-plugin:  <release>11</release>

Without the javadoc override the plugin inherits --release 8 from the
parent profile's @options file, causing javadoc generation to fail with
"package jdk.jfr does not exist".
