Terminology fixes

We're updating ZAP to use less controversial terminology terms: https://github.com/zaproxy/zaproxy/issues/6029
Are you ok accepting a PR which changes white / black list terms _in_documentation_ to allow / deny lists?
No payloads will be updated, just the docs.
We import fuzzdb when there are changes changes so if we just fix this in ZAP then it will just get overwritten next time..
