Fix bracketed paste in terminal on middle click (#52158)

## Context

**Current Behavior:** Middle click pastes multiple lines of text and
runs each as an individual terminal command
**Expected Behavior:** On Linux middle click should use bracketed paste
to paste multiple lines and wait for the user to hit "Enter" before
running all commands together like when pressing Ctrl+Shift+V

Steps to reproduce old behavior: 
1. Open terminal 
2. Copy multiple lines of text from outside the terminal
3. Middle click to paste text in terminal
