[Test][Accuracy] Add accuracy evaluation config for InternVL3_5-8B (#3964)

### What this PR does / why we need it?

To continuously monitor the accuracy of the InternVL3_5-8B model, this
PR adds the corresponding configuration file to the CI. We need to add
the `-hf` suffix to avoid incompatibility with the `lm-eval`
preprocessor.

### How was this patch tested?

`pytest -sv ./tests/e2e/models/test_lm_eval_correctness.py --config
./tests/e2e/models/configs/InternVL3_5-8B.yaml`
