odo list does not work if KUBECONFIG env var points to multiple kubeconfig files

[rm3l]

/kind bug

What versions of software are you using?

Operating System:
Fedora 37

Output of odo version:
odo v3.8.0 (cb5d20d)

How did you run odo exactly?

I recently set my local KUBECONFIG environment variable set to a list of kubeconfig files, to separate the different clusters that I have.

KUBECONFIG=/home/asoro/.kube/config:/home/asoro/work/projects/odo/.ci_kubeconfig odo list

Actual behavior

$ KUBECONFIG=/home/asoro/.kube/config:/home/asoro/work/projects/odo/.ci_kubeconfig odo list
 ✗  KUBECONFIG not found. Unable to retrieve cluster information. Please set your Kubernetes configuration via KUBECONFIG env variable or ~/.kube/config

Expected behavior

The KUBECONFIG environment variable can be a list of separate kubeconfig files, which is valid per the official doc. This list is colon-delimited on Linux and Max, and semicolon-delimited on Windows.
So odo list should work and use the result of merging the files listed in KUBECONFIG.

Any logs, error output, etc?

odo list seems to handle this environment variable differently. Other commands, like odo dev, odo describe component, ... work fine with the same KUBECONFIG env var.

I actually noticed this issue via the OpenShift Toolkit plugin for JetBrains IDEs:

Below is the complete stack trace of the plugin:

Reopening as it is still relevant to me to make odo list work consistently in this case. All the other commands work correctly.
