fix: Report error when os.CreateTemp fails (to be consistent with other uses)

[dougdonohoe]

Description

A error returned from os.CreateTemp is not wrapped in the case of docker and podman uses. This changes the code to be consistent with the two other uses, containerd and remote.

I ran into this and had no visibility as to why os.CreateTemp failed.

I didn't add tests given this is just a small change in-line with the existing examples.
