Paste with promptable sections (powered by AI)

# Description of the new feature/enhancement
Often times, you copy commands from a website that has placeholders in it, which you are supposed to replace. Currently, on almost all terminals, you either copy the entire thing, move the cursor to where the placeholder is there and overwrite it. Or if you are like me, you copy it into Notepad, replace the placeholder with your parameter and then paste it into the terminal. Both are not very convenient.

# Proposed technical implementation details (optional)

Not exactly sure how the syntax should look to distinguish placeholders from actual text, but Windows Terminal could decide one. When a string with placeholders is copied, Windows Terminal should allow you to press Tab and to simply overwrite each placeholder with a parameter you want. The way Visual Studio does small code snippets could be an inspiration.

No files, tests, or entry points are named. First clarify the placeholder syntax, how copied text is detected, and the Tab-based editing behavior; done should include an agreed interaction design and acceptance criteria for replacing each placeholder in Windows Terminal.
