Improve jaeger traces on the aggregator

Description

This PR makes two modifications on the event traces generated while responding to a task on the aggregator:

1. Removed the Bump gas price event, in favor of Gas price set so we not only get information of the used gas prices when a bump occurs, but also on the first attempt.
2. Added the effective_gas_price attribute to the Task Sent to Ethereum event, so we know exactly what was the gas price fee after sending the transaction (which may be lower than the one specified, see EIP-1559)
3. Removed a LogTaskError on sendAggregatedResponse as it was being duplicated

How to test

First test, normal behavior

1. Start all services, including telemetry and metrics (grafana dashboard)
2. Send a task, with make batcher_send_sp1_task
3. Wait for the task to be verified
4. You should see that the dashboard "# Bumps Sending Responses to Ethereum" is at zero.
5. You should see on jaeger these events:

Second test, retry behavior

1. Simulate a retry in the aggregator by adding the following to the avs_writer.go

178	if i < 3 {
	    i++
	    return nil, fmt.Errorf("My error")
        }

2. Start all services, including telemetry and metrics (grafana dashboard)
3. Send a task, with make batcher_send_sp1_task
4. You should see that the dashboard "# Bumps Sending Responses to Ethereum" is now indicating 3 bumps
5. You should see on jaeger these events:
