Specify default VSCode project configuration

[criznach]

I've defined two different project configurations in esp_idf_project_configuration.json. When I start up VSCode, the toolbar says "No Configuration Selected". Yet I can still build and a binary is produced. How can I force a default configuration so my pre and post-build commands always get executed? I don't ever want to allow a build with no configuration selected.

Where does the default configuration come from?
