Cannot create a binding to output Esc only

### Windows Terminal version

_No response_

### Windows build number

_No response_

### Other Software

_No response_

### Steps to reproduce

Try to create a new binding to output Esc character (\x1B)

### Expected Behavior

Pressing the binding should send Esc character to the app

### Actual Behavior

Nothing gets sent, which in WSL can be confirmed by running `cat` program.
Interestingly, it is possible to create a binding that sends Escape Sequences, e.g. `Alt-q` (\x1Bq), but not the Esc itself.

Start by reproducing the binding in Windows Terminal and verify the behavior with the `cat` program in WSL. Trace the binding path for outputting `\x1B`, compare it with the working `Alt-q` escape sequence, and consider the issue done when pressing the Esc-only binding sends the character to the app.
