Filter diagnostics based on classpath/imports about lsp4jakarta

[kathrynkodama]

Possible design decision around if we should show diagnostics if the API is not on the classpath, but it is clear they are intending to use that API given the import statements. We should compare to LSP4MP and JDT LS

In the below screenshot, we should not deliver the diagnostic on HelloServlet as the WebServlet import is incorect.
