RFR: 8310868: Thread.interrupt() method's javadoc has an incorrect {@link}

[Jaikiran Pai]

Can I please get a review of this trivial change which fixes a javadoc issue reported in https://bugs.openjdk.org/browse/JDK-8310868?

I ran `make docs-image` locally with this change and the link is now correctly rendered in the generated javadoc.
