Description of problem:

Workaround to apply `"quality": "stable"` in the products.json does NOT seem to work e.g. https://eclipse.dev/che/docs/stable/administration-guide/editor-configurations-for-microsoft-visual-studio-code/ 

  settings.json: |
    {
      "window.header": "Developer Sandbox Staging Cluster"
    }
  configurations.json: |
    {
      "extensions.install-from-vsix-enabled": false
    }
  product.json: |
    {
      "quality": "stable"
    }

Prerequisites (if any, like setup, operators/versions):

Steps to Reproduce

• start a workspace from https://github.com/che-incubator/quarkus-api-example
• ERROR: once workspace is started the pre-release version of Quarkus extension is installed, not the stable one

Actual results:

 The pre-release version of extensions is installed by default 

Expected results:

 The stable version of extensions is installed by default **

Reproducibility (Always/Intermittent/Only Once):

Build Details:

Additional info (Such as Logs, Screenshots, etc):

this is a regression since in Dev Spaces 3.19 the released version of the extension is installed by default:

However, even on 3.19 the "Extension" view drop-down selection defaults to "Pre-release"
