[DOCS] Add troubleshooting for RPC request timeouts

[sbvegan]

Brief Description of the Docs Request

Sometimes RPC trace calls will timeout, attaching a timeout to the param request gives the node sufficient time to trace the block. Relevant RPC methods:

• debug_traceCall
• debug_traceTransaction
• debug_traceBlockByNumber
• debug_traceBlockByHash

Description of the Documentation You'd Like

Adding a troubleshooting guide or callout for transactions that are timing out.

Additional Context

Sample request timing out:

$ curl <rpc-endpoint> -X POST -H "Content-Type: application/json" --data '{"method":"debug_traceBlockByNumber","params":["0xB607A4", {"tracer": "callTracer"}],"id":1,"jsonrpc":"2.0"}'

> {"jsonrpc":"2.0","id":1,"result":[{"error":"execution timeout"}]}

Adding "timeout": 300s to the params gives the node sufficient time to trace the block.
