Missing documentation for worker concurrency values

[marzn]

Bug Description

In the docs there is only a basic documentation of the concurrency parameter:
https://docs.n8n.io/hosting/scaling/queue-mode/#configure-worker-concurrency

The code logs a warning which sounds critical if you have a concurrency less than 5:

n8n/packages/cli/src/commands/worker.ts

Line 154 in 8cfc9bc

'Concurrency is set to less than 5. THIS CAN LEAD TO AN UNSTABLE ENVIRONMENT. Please consider increasing it to at least 5 to make best use of the worker.',

I would expect if this is critical, the documentation should mention that a concurrency less than 5 is critical and why this could lead to an unstable environment.

Expected behavior

There is an explanation why a concurrency less than 5 could lead to an unstable environment.
