Fix test load image issue (Project-MONAI#8297)

Fixes Project-MONAI#8274 .

### Description

The new test has already tested with the same 24.08 + A100 env.

I did some tests but cannot reproduce the original test case error
(there are NaN values or significant small/large data). Since only 24.08
base image has the issue (24.10 does not have), I decided to use a
different test case for 24.08 and prepared this PR
