Upstream implementations checks for all calls at MEDIUM severity and the the specific functions at HIGH severity. Unsure if we want to replicate this, as it might be a bit heavy performance wise and Ruff/flake8-bandit has no way of separating the severity levels right now. Just copied upstream implementation for now

I decided to reduce the rule scope for the same reason.
