What feature(s) are you requesting?

#2050 indicates most of tests can run fine with Java 17. Maybe we can move to Java 17 for all templates.

1. Target version needs to be updated everywhere to 17, examples:
   

   DataflowTemplates/pom.xml

   Line 34 in ff14f97

   <java.version>11</java.version>

   
   

   DataflowTemplates/plugins/core-plugin/pom.xml

   Line 35 in ff14f97

   <maven.compiler.source>11</maven.compiler.source>

   
   

   DataflowTemplates/v2/pom.xml

   Line 421 in ff14f97

   <maxJdkVersion>11</maxJdkVersion>

2. Containers need to be updated to java17 (example:

   DataflowTemplates/plugins/templates-maven-plugin/src/main/java/com/google/cloud/teleport/plugin/maven/TemplatesReleaseFinishMojo.java

   Line 88 in ff14f97

   "gcr.io/dataflow-templates-base/java11-template-launcher-base-distroless:latest",

   ).

for future reference, this unblocks #2136
