Manual models always take precedence over generated models, so there is
no point in keeping the generated models.

the corresponding df-gen models.

python3 /Users/owen-mc/workspace/codeql-home/codeql/java/ql/src/utils/modelgenerator/GenerateFlowModel.py /Users/owen-mc/db/java/openjdk17 --with-summaries --with-neutrals
