Fix parca-agent for parca-devel

[metalmatze]

With the move to the Otel eBPF-based profiler, the parca-agent got a new CI pipeline.
As part of that, the timestamp was removed from the container image tag.
We have two options to unblock parca-devel deployments again.

1. Add the timestamp to the container image
2. Update the automated deployments not to expect the timestamp

Unfortunately, I was unable to find it quickly and don't have the time to investigate fixing the automation script right now.
Where would we remove the timestamp usage from the pipeline?
