Bug Description

The contribution markdown contains the wrong version of Node referenced.

To Reproduce

1. Download n8n repo
2. Install Node 18.10
3. Receive error on pnpm install command

Expected behavior

pnpm install should proceed correctly.

Operating System

Pop!_OS 22.04 LTS

n8n Version

1.50.0 (master)

Node.js Version

18.10.0

Database

SQLite (default)

Execution mode

main (default)

So my PR #10003 might not be right. When trying pnpm start after pnpm build on node 18.12 it fails saying n8n requires v18.17.0

I think the versions should be bumped to at least 18.17 as a requirement if that is the case.

Great spot, as our minimum is 18.17.0 we should probably use that in the docs.

Let me check with the team to confirm.
