fix(app): stop the terminal from typing its version reply into the shell (#8419)

Browse Source 
The browser terminal is a renderer and leaves protocol replies to the
daemon, but it still answered XTVERSION (CSI > q) and DECRQSS
(DCS $ q ... ST). Those replies went out through onData as if the user
had typed them, so a query from a program in the shell left text like
">|xterm.js(6.1.0-beta.292)" on the next input line. Both queries are
now swallowed with the other protocol queries.

Fixes #8111
