Pre commit fixes (#911)

* Define gen_exclude anchor at first use to resolve warning

This was the warning:

[WARNING] Unexpected key(s) present at root: gen_exclude

Also fix the regex: the old pattern was missing the ^ before the second alternative

* Remove requirements-txt-fixer

To avoid this line:

```
fix requirements.txt.................................(no files to check)Skipped
```

* Change the commit hash in .github/workflows/bandit.yml
