Fix directory path type

[armantorkzaban]

Fixes the following issue on Kubernetes with the type of Directory:
MountVolume.SetUp failed for volume "proc" : hostPath type check failed: /proc-host is not a directory

[marceloamaral]

@armantorkzaban, we exclusively utilize /proc-host for the Kind cluster due to the limitation of directly mounting the host /proc folder. This serves as a workaround.

If you have an error related to /proc-host, it indicates that the Kind cluster may not have been created correctly, or the Kepler deployment might not be configured for a Kind cluster.
