fix so that commands with && > | these operator work

[rogdevil]

previously if we had to run commad like
echo "/** @type {import('next').NextConfig} */" > next.config.js or
cd project && npm i
these won't work as exec.Command does not store standard output or standard err it a command fail it simply retuns an error thus causing us problem with yml files where we need to do custom nginx file addition or configuration file changes.
fix is to treat each command as a bash command as whole.

Allowing pipes and redirects is a larger concern

Yeah we need these when we need to append to a file like we needed in next.conf.js
