docs(qrsvg): fix command example (#11436)

Window and tab titles are changed by emitting an unprintable escape
sequence to the terminal. These escape sequences do not play nicely
with the TAB character on multiple terminal emulators--they create
un-deletable characters on the first line after command execution.
Sending "\r" after changing the window and tab titles allows all
characters on the first line to be deleted.

Fixes #11314
