Versions 3.0 and higher of `typeguard` can't check the jsii protocol interfaces and produce a noisy warning. Because `constructs` hadn't been updated for a while, and it had been generated with an old version of `jsii-pacmak` that was forcing `typeguard` to `2.13`, no-one had noticed all the changes to `pacmak` that try to support a newer version of `typeguard`, because in practice it never ended up being installed (all CDK projects will install `constructs` which was keeping `typeguard` at an old version). Revert to that old version, and stick at it until we can fix up our generated Python bindings to be more modern.
