This PR updates all references to the jetbrains-gateway module to use the new coder/jetbrains module with a simplified configuration format.

Summary of Changes

Module Updates

• Module name: Changed from jetbrains_gateway to jetbrains
• Module source: Updated from registry.coder.com/modules/jetbrains-gateway/coder to registry.coder.com/modules/coder/jetbrains/coder
• Version constraint: Set to "~> 1.0" for automatic minor updates while preventing breaking changes
• Configuration: Simplified to only include essential parameters (count, source, version, agent_id, folder)

New Module Format

module "jetbrains" {
  count    = data.coder_workspace.me.start_count
  source   = "registry.coder.com/coder/jetbrains/coder"
  version  = "~> 1.0"
  agent_id = coder_agent.example.id
  folder   = "/home/coder"
}

Files Updated

Documentation (3 files):

Folder Path Preservation

• Most templates use /home/coder
• Devcontainer templates (docker-envbuilder, gcp-devcontainer) use /workspaces
• Original folder paths preserved from previous configuration

Testing

All changes maintain the same functionality while pointing to the new module location. The simplified configuration reduces complexity while providing the same JetBrains IDE integration capabilities.
