how can I send my logs to the otel collector from my gin app without outputting it in a file? (I tried to use otel.SetLogger function but it does not seem to work)

If you are using docker you can use logging drivers https://github.com/SigNoz/logs-benchmark/blob/0b2451e6108d8fa5fdd5808c4e174bd52b9d55d3/signoz/signoz-client/docker-compose.yaml#L47

I am deploying my application to aws ecs...so I guess the only option for me is to deploy otel collector as a sidecar and let it read my application logs from the file( where my application writes it)?
