Label agent plugin telemetry separately from VS Code extension telemetry

**Issue:**
agetnplugin telemetry is under vscode and update hooks script to make it separate. In this https://github.com/microsoft/GitHub-Copilot-for-Azure/tree/main/plugin/hooks/scripts folder, there are both .ps1 and .sh files which are basically identical in operation. Right now, skills and file references and all telemetry under these paths ".vscode/agent-plugins/github.com/microsoft/azure-skills/.github/plugins/azure-skills/skills//SKILL.md", ".vscode-insiders/agent-plugins/github.com/microsoft/azure-skills/.github/plugins/azure-skills/skills//SKILL.md" , ".agents/skills//SKILL.md" are labelled as Visual Studio Code and Visual Studio Code - Insiders respectively. we need to distinguish agent plugins and skills from github copilot for azure extension in .agents folder.
