Apply the rich rich.logging.RichHandler gracefully

[datajoely]

Description

In order to enable the rich logging handler via an external plugin we currently intercept the way that the KedroSession parses the contents of conf/base/logging.yml and ensure that the console key is updated to use the right handler.

I tried for agest to intercept the handlers after creation and change them dynamically through approaches like this but this is the only mechanism I could get to work.

Potential solutions to evaluate:

• Work out the correct way to mutate the global logging objects so that the given log-handler is ignored without the need for monkey patching.
• Given rich is becoming quite mature at this point I think there is a decent argument for this becoming the default handler in the core Kedro library.
