Standard Doclet documentation does not mention {@summary} for @deprecated

A DESCRIPTION OF THE PROBLEM :
It appears the Standard Doclet supports using the {@summary} javadoc tag within the @deprecated block tag to include more than the first sentence in the summary.

However, the [Documentation Comment Specification for the Standard Doclet|https://docs.oracle.com/en/java/javase/15/docs/specs/javadoc/doc-comment-spec.html] does not mention this.

It should therefore by adjusted by:
- Mentioning {@summary} usage in the section about @deprecated
- Changing the {@summary} section to mention that it is allowed for the @deprecated block tag as well

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create javadoc for the class provided below and compare what is included the summary about deprecation.


---------- BEGIN SOURCE ----------
public class Test {
    /**
     * @deprecated First sentence. Second one.
     */
    @Deprecated
    public void test1() {
        
    }
    
    /**
     * @deprecated {@summary First sentence. Second one.}
     */
    @Deprecated
    public void test2() {
        
    }
}
