ci: update Maven build commands in GitHub Actions workflows

- In build-and-run-example-project.yml:
  - Modify 'Build and Install' step to use 'mvn install -DskipTests=true'
  - This change ensures tests are skipped and improves build efficiency

- In maven.yml:
  - Update 'Build with Maven' step to include '-DskipTests=true'
  - This change consistently skips tests across both workflows
