Upgrade Javadoc URLs for JDK 17 based build

Prior to this commit, the Javadoc task would fail on
`spring-context-indexer` and `spring-instrumentation`. It seems that
missing remote docs or HTTP redirects were failing the process.

This commit removes the missing published Javadocs and updates the
version for the JDK API.
