This script is used to get the models for which to run slow CI.
A new model added in a pull request will be included, as well as models specified in a GitHub pull request's comment
with a prefix `run-slow`, `run_slow` or `run slow`. For example, the commit message `run_slow: bert, gpt2` will give
`bert` and `gpt2`.
Usage:
```bash
python utils/pr_slow_ci_models.py
```
