Issue Summary:

Forge App with jira:fullPage Forge module is not accessible on Jira-only Cloud instances(Cloud instances which only have Jira site and not confluence).

Steps to Reproduce

• Make sure that Cloud instance is only having Jira site only. 
• Deploy and Install a Forge app with jira:fullPage module app on a Cloud site with only Jira app. Confluence App should not be there in site.
• Access app with url mentioned in doc Navigation - Full Page Module. Also monitor network tab in browser dev console.

  https://<your-site>.atlassian.net/forge-apps/a/<app-id>/e/<forge-environment-id>/r/<route-prefix>/<app-route> 

• We find error in graphql response with statusCode 404 and classification as ProductMissingException.

  {
    "errors": [
      {
        "message": "TCS did not contain requested product: confluence",
        "locations": [],
        "extensions": {
          "product": "confluence",
          "cloudId": "<cloud-id",
          "errorSource": "GRAPHQL_GATEWAY",
          "statusCode": 404,
          "agg": {
            "severity": "NORMAL",
            "ugcPiiSafe": true
          },
          "classification": "ProductMissingException"
        }
      }
    ],
   

• We don't observe this error when Cloud site has Jira and confluence. 

Expected Results

• Forge Jira fullPage module should work for site not having Confluence application.

Actual Results

• In Browser dev panel for graphql request we find response with statusCode 404 and classification as ProductMissingException.

  {
    "errors": [
      {
        "message": "TCS did not contain requested product: confluence",
        "locations": [],
        "extensions": {
          "product": "confluence",
          "cloudId": "<cloud-id",
          "errorSource": "GRAPHQL_GATEWAY",
          "statusCode": 404,
          "agg": {
            "severity": "NORMAL",
            "ugcPiiSafe": true
          },
          "classification": "ProductMissingException"
        }
      }
    ],
