Optionally "pipe" into interpreter vs shebang

[sourishkrout]

This would make it possible to have cells with SQL or REDIS queries and imply their client (psql, redis-cli) connection without cluttering the cell, e.g. this cell https://app.runme.dev/cell/clpx627zy001pnqb4ypauutqx wouldn't use echo "INFO" to pipe into the redis-cli -p 16379, instead one would configure the cell interpreter and tick "pipe into" or something.
