feat: clearer aliases for event filter boolean operators — radicle-ci-broker

The boolean operators “And”, “Or”, and “Not”, all take a list of filter expressions as operands. In normal boolean logic they take two or one, and the list case can be a little confusing to read. Introduce aliases “AllOf”, “AnyOf”, and “NoneOf”. These are merely aliases for the operators, with the exact same semantics.
