[BUG] Kamelet: spec/definition/properties/remoteURI/example is removed after sync

[igarashitm]

Describe the bug
If I paste this Kamelet into source editor and click sync button

kamelet

apiVersion: camel.apache.org/v1alpha1
kind: Kamelet
metadata:
  name: jms-amqp-10-source
  annotations:
    camel.apache.org/kamelet.support.level: "Stable"
    camel.apache.org/provider: "Apache Software Foundation"
    camel.apache.org/catalog.version: "4.0.0-SNAPSHOT"
    camel.apache.org/kamelet.group: "JMS"
    camel.apache.org/kamelet.namespace: "Messaging"
  labels:
    camel.apache.org/kamelet.type: "source"
    camel.apache.org/requires.runtime: camel-k
spec:
  definition:
    title: "JMS - AMQP 1.0 Source"
    description: "Consume data from any AMQP 1.0 compliant message broker by using the Apache Qpid JMS client."
    required:
      - destinationName
      - remoteURI
    type: object
    properties:
      destinationType:
        title: "Destination Type"
        description: "The JMS destination type (queue or topic)."
        type: string
        default: queue
      destinationName:
        title: "Destination Name"
        description: "The JMS destination name."
        type: string
      remoteURI:
        title: "Broker URL"
        description: "The JMS URL."
        type: string
        example: "amqp://my-host:31616"
  dependencies:
  - "camel:jms"
  - "camel:amqp"
  - "camel:kamelet"
  template:
    beans:
      - name: connectionFactoryBean
        type: "#class:org.apache.qpid.jms.JmsConnectionFactory"
        property:
          - key: remoteURI
            value: '{{remoteURI}}'
    from:
      uri: "jms:{{destinationType}}:{{destinationName}}"
      parameters:
        connectionFactory: "#bean:{{connectionFactoryBean}}"
      steps:
      - to:
          uri: "kamelet:sink"

The backend returns empty flows it was missing - before template/property/key, non-empty response is returned once it's added.

{"flows":[],"metadata":{},"properties":{}}

To Reproduce
Steps to reproduce the behavior:

1. Choose Kamelet in New Route dropdown box
2. Paste the kamelet YAML
3. Click sync button
4. See response JSON in the browser network tab

Expected behavior
Proper integration JSON is returned

[igarashitm]

The problem was in the kamelet code, - was missing right before property/key. The non-empty response is returned once it's added.

Now the only issue with this is that remoteURI/example is removed after sync.
