When setting the proxyBeanMethods attribute to false the @Bean methods are not proxied and this is similar
to removing the @Configuration stereotype. In this scenario, @Bean methods within the @Configuration annotated
class operate in lite
mode, resulting in a new bean creation each time the method is invoked.
For Singleton beans, this could cause unexpected outcomes as the bean is created multiple times instead of being created once and
cached.
The rule raises an issue when the proxyBeanMethods attribute is set to false and the @Bean method of a
Singleton bean is directly invoked in the @Configuration annotated class code.
