Update jackson databind 2.9.9.3+

Fixes more gadget vulnerabilities with ehcache and logback in the classpath.

Note that the fix is in 2.9.9.2. However, that version broke things. Waiting for 2.9.9.3 to be released.  https://github.com/FasterXML/jackson-databind/issues/2395

TinkerPop is not directly affected hence low priority (let alone that the fix isn't even available).
