Pin java template maven dependency to latest known good version.

[dixler]

This commit pins org.apache.maven.plugins:maven-compiler-plugin to 3.5.1 to resolve failing builds for UBI images on pulumi-docker-containers.

pulumi/pulumi-docker-containers#127

Context

pulumi-docker-containers has 2 different java builds.

• Debian (passing)
• UBI (failing)

UBI is failing running a test that runs the java pulumi/template with the following error message:

Error: umi:pulumi:Stack test-env4268922448-p-it-ea7a4b0c6d-test-env42-4bd12ab9 [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.10.1:compile (default-compile) on project test-env4268922448: Fatal error compiling: error: release version 11 not supported -> [Help 1]

The Debian and UBI images differ on the version of org.apache.maven.plugins:maven-compiler-plugin

When running locally on the image with the modified pom.xml the build succeeds on 3.5.1, but the tested versions including 3.6.0 and latest (3.11.0 as of writing) provided the following error as of writing when running pulumi pre inside the UBI docker image:
