Streamlining Azure DevOps extension development

This post details a new workflow for developing Azure DevOps extensions that allows for debugging and hot-reloading directly from a local development environment (IDE/editor) instead of redeploying to the marketplace for each change. It outlines specific steps: reconfiguring `vss-extension.json` with a `dev.json` override for local development, updating `webpack.config.json` to enable source maps and configure the dev server, setting up Firefox debugging in VS Code's `launch.json`, installing and running `webpack-dev-server`, and deploying a development version of the extension using `tfx-cli` with the `dev.json` override. This approach leverages Azure DevOps' capability to load content from localhost, enabling hot reloading and debugging in Visual Studio Code.
