Argument list too long if step argument has a very long argument

[dahuriner]

Describe the bug
We have some big workflows and we hit the following error:

exec /bin/argo-events: argument list too long

After digging a bit, we realized it's because our workflow is big. After deleting some tasks from the workflow, it started to work fine. I checked some issues on argo-workflows repo and I noticed that this issue(argoproj/argo-workflows#12190) has been reported before and then eventually fixed on argo-workflows. I was thinking we should fix it in argo-events too.

To Reproduce
Steps to reproduce the behavior:

1. Create a big workflow. You can duplicate more than 50 tasks, so you can hit the limit.
2. Publish it as a sensor.
3. Check argo-events log for that sensor.
4. You should see this error message: exec /bin/argo-events: argument list too long

Expected behavior
A clear and concise description of what you expected to happen.
