FP in S3749 when spring class is not a singleton

As explained by S3749, spring classes are singleton by default, but @Scope annotation can change this behavior. From the documentation:
As a rule of thumb, you should use the prototype scope for all beans that are stateful
In addition, you can define a custom scope, that could also change it.

We should therefore report an issue only when the scope is known, and not "prototype".

@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)
@Scope("prototype")
@Scope(value = "prototype")
@Scope("custom-scope")

Note: S3750 already detect @Scope annotations.
