test: fix stale conftest docstring for the retired native binary (#292) (#293)

The codeanalyzer_backend_path fixture documented the JVM-free native binary
(python -m codeanalyzer_java), which no longer exists. The analyzer's default is
now the bundled codeanalyzer-*.jar run on a cached JDK. The fixture behaviour is
unchanged (still returns None); only the docstring is corrected.
