SpringBoot Add @ ConditionalOnMissingBean annotation on the graphQlRouterFunction bean

🎁 Enhancement

When users have time, they need to rewrite routing rules so that they can do more custom actions; Add @ ConditionalOnMissingBean annotation on the graphQlRouterFunction bean. I hope my suggestion is useful to you

Sorry but we cannot apply this enhancement. RouterFunction beans are the common way to contribute routes to the functional web framework. Applying this condition would turn this off as soon as there is a route contributed by some other component, even if it's got nothing to do with GraphQL.
