`unwrap` rule it's too noisy

Reference: ...

# Proposed Solution

- [ ] Remove the rule
- [x] Fork and improve the rule:

- [ ] Only do it for unwrap and assume that expect means that someone at least thought about why it cannot happen.
- [ ] Ignore any file in examples/, tests/, benches/ (if not already done)
- [ ] Ignore #[test] functions
- [ ] Create a custom clippy lint, so that we can prevent the warnings from semgrep by checking/fixing them locally first
