[ci] Bump containerd version to 1.7.2 in holodeck config

Containerd 1.7.0 is the first release that supports CDI. CDI devices were exclusively
passed to containerd via annotations.
https://github.com/containerd/containerd/releases/tag/v1.7.0

In containerd 1.7.2 support was added for making use
of the new CRI fields 'Config.CDIDevices' so that CDI devices could be passed through the CRI
instead of annotations.

This commit updates our holodeck configuration so that containerd 1.7.2 is installed
in our e2e test machines.
