Readme: (Redis) reactive hints not idiot proof

[Brutus5000]

So in the Spring world if someone gives me a checkbox saying does this support reactive yes/no so far it always indicated that this has additional support for WebFlux.

It took me a while to look into the Spring configuration classes and figure out that this is not the case here. At least for the Redis dependency reactive support means that it only supports Webflux.

Maybe instead of a column reactive yes/no, a column WebType servlet/webflux would be better?
