coturn: fix unescaped backticks corrupting generated README + stray error

The "Adding a new service that needs TURN" example in coturn.sh's
write_readme heredoc had one unescaped backtick pair (`sudo ./setup.sh
coturn`) while every other backtick in the same heredoc was correctly
escaped. Since write_readme's heredoc is unquoted (intentionally, so
$DIR-style interpolation works elsewhere in the file), bash treated it
as a command substitution: it actually tried to execute `sudo
./setup.sh coturn` at install time, printed "sudo: ./setup.sh: command
not found" to the terminal on every coturn install, and silently
dropped the intended text from the generated README.

Found while verifying the shared-coturn multi-consumer flow end-to-end
(coturn install -> asterisk + 2 mattermost instances all registering
concurrently) — confirmed working correctly otherwise: three distinct
credential files, no collisions, all three referencing the same host/
port, and reruns correctly reuse the cached credential instead of
regenerating.
