Describe the bug 📉
When running sudo bench setup production <user> the nodejs path is wrong in supervisor.conf, bench loads node from system path instead using the user environment installed like nvm install 18.
This behavior creates problem on OS which ship node < 16 like Ubuntu 22 and consequentially fail to start socketio process
This is the affected row in supervisor.conf

[program:frappe-15-node-socketio]
command=/usr/bin/node /home/ubuntu/frappe-15/apps/frappe/socketio.js

To Reproduce 📃
Steps to reproduce the behavior:
Install node

nvm install 18
sudo bench setup production <user>

Expected behavior 📈
supervisor.conf should use node from user environment like:
command=/home/ubuntu/.nvm/versions/node/v18.20.5/bin/node /home/ubuntu/frappe-15/apps/frappe/socketio.js

Possible Solution 📑
In git which("node") should use user context instead of sudo

	config = template.render(
		**{
			"bench_dir": bench_dir,
			"sites_dir": os.path.join(bench_dir, "sites"),
			"user": user,
			"use_rq": use_rq(bench_path),
			"http_timeout": config.get("http_timeout", 120),
			"redis_server": which("redis-server"),
			"node": which("node") or which("nodejs"),
