Fix lint-java job: Add Java 11 setup for googlejavaformat compatibility

[Copilot]

The axel-op/googlejavaformat-action@v3.6.0 requires Java 11, but ubuntu-latest runners now default to Java 17+, causing the lint-java job to fail.

Changes

• Added JDK 11 setup step before googlejavaformat-action in the lint-java job

- name: Set up JDK 11
  uses: actions/setup-java@v3
  with:
    distribution: 'temurin'
    java-version: '11'
- uses: axel-op/googlejavaformat-action@fe78db8a90171b6a836449f8d0e982d5d71e5c5a #v3.6.0
  with:
    args: "--set-exit-if-changed"

Original prompt

The lint-java GitHub Actions job fails due to an incompatibility between the default Java version (typically Java 17+) on ubuntu-latest runners and the axel-op/googlejavaformat-action (v3.6.0), which is best supported on Java 11. To resolve the error, edit the 'lint-java' job in .github/workflows/test.yml to insert the following step prior to the googlejavaformat action:

- name: Set up JDK 11
  uses: actions/setup-java@v3
  with:
    distribution: 'temurin'
    java-version: '11'

This ensures the googlejavaformat action runs with Java 11 and the workflow linting step will function correctly.

Apply this change on the dev branch.
