fix(tests): use assert.CollectT in TestContainerCMDAgentMonitoringRuntimeExperimental (#11499)

Updates TestContainerCMDAgentMonitoringRuntimeExperimental to use the assert.CollectT instead of the testing.T inside require.EventuallyWithT.

This prevents the code from failing on the first pass of require.EventuallyWithT. Now it retries transient assertion errors up to the timeout.

(cherry picked from commit f32807c)
