How to set up and validate locally

Numbered steps to set up and validate the change are strongly suggested.

1. Create a workspace from a devfile which has the attribute gl/use-vscode-1-81: false

   schemaVersion: 2.2.0
   variables:
     registry-root: registry.gitlab.com
   components:
     - name: tooling-container
       attributes:
         gl/inject-editor: true
         gl/use-vscode-1-81: false
       container:
         image: registry.gitlab.com/vtak/gitlab-web-ide-vscode-fork/ubuntu:24.04-workspace

2. Open up the workspace and run the following command in the terminal to verify new version of VS Code(fork) is injected - /projects/.gl-tools/code-server/bin/gitlab-webide-server --version . The expected output is

   1.85.2
