Subject: [PATCH] fix: data tables available on all n8n plans, remove redundant
 pitfalls (#656)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Data tables are available on self-hosted n8n too, not just enterprise/cloud.
Removed incorrect availability restriction from tool description and docs.
Removed redundant pitfalls (API key requirement implicit, plan restriction wrong).

+- **Incorrect data tables availability info**: Removed "enterprise/cloud only" restriction from tool description and documentation — data tables are available on all n8n plans including self-hosted
+- **Redundant pitfalls removed**: Removed "Requires N8N_API_URL and N8N_API_KEY" and "enterprise or cloud plans" pitfalls — the first is implicit for all n8n management tools, the second was incorrect
