The VS Code's JSON language server expects a 'json/schemaAssociations'
notification to associate JSON files to JSON schemas. This activates
capabilities like code completion, validation and hover without the need
to add a '$schema' key.
This change implements an extension of the JsonBasedLanguageServer that
registers as ServerInitializerObserver and sends the
'json/schemaAssociations' notification on the 'onServerInitialized'
event.
