[BUG] otel-agent binary not present in Docker image

[nickvecelliooo]

Agent Environment
Initially found on 7.55.2, also tested on 7.55.3, latest, and 7-beta (the most recent push to dockerhub)

Describe what happened:
When otelCollector.enabled is set to true in the Helm chart, a container is added to the pod called otel-agent, with a command of

  command: ["otel-agent", "-foreground", "-config={{ template "datadog.otelconfPath" . }}/datadog.yaml"]

When the container tries to start, the following occurs:

    message: 'failed to create containerd task: failed to create shim task: OCI
      runtime create failed: runc create failed: unable to start container
      process: exec: "otel-agent": executable file not found in $PATH: unknown'

Describe what you expected:
The otel-agent binary to be present and the container to start

Steps to reproduce the issue:
Install the Datadog Helm chart with the below

datadog:
  apiKey: <yoink>
  clusterName: demo
  otelCollector:
    enabled: true

and the pod will not start.

This can also be tested in the images on dockerhub

$ docker run -it datadog/agent:7-beta bash
root@a5bfaa78b3f9:/# find / -name 'otel*'
/opt/entrypoints/otel-agent
root@a5bfaa78b3f9:/# cat /opt/entrypoints/otel-agent 
#!/usr/bin/env bash
set -euo pipefail

exec /opt/datadog-agent/embedded/bin/otel-agent --config /etc/datadog-agent/otel-config.yaml
root@a5bfaa78b3f9:/# /opt/datadog-agent/embedded/bin/otel-agent
bash: /opt/datadog-agent/embedded/bin/otel-agent: No such file or directory
