VS Code Knowledge Pill: Profiles switching using Workspaces

I've longed for a profile/settings switcher in VS Code that loads specific settings or extensions depending on a specific project or what programming language I'm using.

We can use VS Code's workspaces to act as a profile switcher.

1. Create an empty workspace
2. Enable extensions for the workspace
3. Configure workspace specific settings
4. Add project to workspace

This workspace is now configured with all the extensions and settings that I need for working on a Rust project.
