repl: Don't send KernelInfoRequest on launch (#14608)

Kyle Kelley created 2 years ago

Closes #14146. This is just for the time being before a networking
refactoring to split reads and writes on the ROUTER/DEALER ZeroMQ
sockets. Some kernels have not been responding with `kernel_info_reply`,
which ends up hanging our shell socket.

Release Notes:

- N/A

Release notes for the REPL feature will be part of its official launch.
