Types solely referenced from Javadoc reported as unused imports

Assume a class referencing a class solely from Javadoc:

```java
import java.util.List;

/**
* {@link List}
*/
class SomeClass {}
```

On JDT 3.19.500, this reports the import as unused, and the cleanup action to remove unused imports would remove it accordingly. Unfortunately, this breaks the Javadoc tooling, as it will complain about the missing reference if run with the `reference` doclint option enabled.

I wonder if [this ticket](https://github.com/eclipse-jdt/eclipse.jdt.core/issues/2481) is related as I think considering the import unused has popped up recently (just a gut feeling).
