Javadoc Markdown Content Assist suggests wrong format for type links.

I'm using Eclipse EE 2025-09 with Java 25. Let's say I'm using the new [JEP 467](https://openjdk.org/jeps/467) Markdown Javadocs, and I create a `FooBarTest` class file. I start start writing a Markdown Javadoc for the class (The `|` indicates my cursor.)

```java
/// Tests of Foo|
public class FooBarTest {
}
```

If I hit `Ctrl+Space` for Content Assist, Eclipse generates:

```java
/// Tests of {@link FooBar}
```

This is incorrect. Using JEP 467 Markdown, Eclipse should generate this:

```java
/// Tests of [FooBar]
```

This ticket is a completely different problem, but is closely related to #4531.
