Update VSCode Fork to receive marketplace settings

MR: feat: Update extensions view gl_mod with extens... (!78 - merged)

Description

Based on Create User-Level Extension Marketplace settings (gitlab#451875 - closed), we need the VSCode Fork to properly handle the following cases:

  • When it receives a extensionsGallery configuration, it should start the main extension marketplace experience.
  • When it does not have an extensionsGallery configuration, it should show the welcome view by default so we can set a value for it in the Web IDE extension.
