Vaadin Flow 2.4.7

Fixes:
- ⧉ Options in the Combo Box's selection list are consistent and not disappearing when first searching and then selecting them. This was happening while using Combo Box with a ComponentRenderer. (#9783). PR:10054. Ticket: vaadin/flow-components#437
- ⧉ No exception would be thrown if servlet class cannot be loaded. This means no more ClassNotFoundException by DevModeInitializer would be thrown for builtin servlets in containers such as Wildfly (#8233). PR:10041. Ticket:8149
- ⧉ Importing binary files (e.g. images) in a frontend file (e.g. TS file) and would not result into MalformedInputException during startup (#9955). PR:9961. Ticket:9926
- ⧉ Always write the package json after updateDefaultDependencies as even if the dependencies are not updated the defaults may be updated. PR:10081. Ticket:10032
Behaviour changes:
- ⧉ Element::removeAllChildren behaviour has been changed (#10128) so that the re-attached node persists its state "removed children" between client-server roundtrips. It wasn't a case before that change, the "clear all" event happens only once after first attach of the node.
  That effectively means that if you have a client-side LitElement component and corresponding LitTemplate java-side component, then once you call Element::removeAllChildren on java-side, it will remove all children on client-side on every attach action. Ticket:10119
