feat: Implement Pipes

[AlaynaMonteiro]

This is how it should work like :

% echo "input\noutput\nhello" | grep input
input

when creating processes from within the shell, create a pipe and attach the stdout of the current process to the write end of the pipe and stdin of the new process to the read end of the pipe. Take a look at how other shells implement it for reference.
