FUSETOOLS2-2508 - Do not register the Camel Language Server for

package.json

every two minutes, there are events didOpen and didClose for
package.json files (not found the reason).
It is polluting Camel logs. Potentially leading to killing the server.
Given that the Camel Language server does not provide anything for
package.json files, the workaround consists in providing a more strict
document selector to discard package.json. As json file, we provide
completion only in VS Code launch.json and tasks.json files.
