fix(osc52): use nvim_chan_send() to stderr for copying (#26690)

The data to be written can be very long, so use nvim_chan_send() instead
of io.stdout:write() as the latter doesn't handle EAGAIN.

A difference of these two approaches is that nvim_chan_send() writes to
stderr, not stdout, so it won't work if client stderr is redirected.
