[infra] Convert examples to bazel integration tests

[restingbull]

1. Disable workspace test.
2. Set .bazelrc for examples that need specific flags.
3. Replace all existing integration tests with the new suites.
4. Fix the version check for later versions of java to not crash with bazel 6. (java_test with bazel 6 and java >11 will fail without more work)

Implementation notes:

• .bazelignore does not work with rules_bazel_integration_test. It must be via --deleted_packages
• The automatic import of files fails as well
• Adding more bazel versions is tedious.
