Description of the new feature/enhancement

Starting with #7293, users can type out wt commands into the Command Palette. Please provide auto-suggestion to users as they type out commands in the Command-Palette (the wt commands). This makes it easier for users to start using the wt command arguments and also speeds up the process for users to execute an action within Windows Terminal.

Proposed technical implementation details (optional)

Extend the current auto-suggestions to include wt arguments.
