Code snippets: In Javadoc view code snippets referring to classes or files ignore @link modifications

The Javadoc view shows the preview of the code snippets that refer to a class or file, but without linking via @link. The `@link` comments are correctly removed, but not applied. In contrast, including the content directly inside the snippet tag ({@snippet : ... }) works as expected.

Java 18 code to reproduce the issue:
Sample.java:
```java
/**
* {@snippet class="Other" region="r1"}
*/
public class Sample { }
```
`Other.java` (contained in the source folder to which `--snippet-path` refers when generating Javadoc):
```java
// @start region="r1"
public class Other {
int field = 42; // @link substring="field" target="System#out"
}
// @end region="r1"
```

**Result:**
In the Javadoc view and in the hover, 42 should be linked to System.out
