[SPARK-41708][SQL][TEST][FOLLOWUP] Match non-space chars in path string

### What changes were proposed in this pull request?

This is a followup of #39610 . The non-greedy mode does not work well if the ending class name appears more than once, like `file://myPath/.../clsName/.../clsName`. We should still use greedy mode, but to match any chars that are not space or comma (comma is used to combine multiple paths in `FileIndex.toString`).

### Why are the changes needed?

make the test framework more stable

### Does this PR introduce _any_ user-facing change?

no

### How was this patch tested?

N/A

Closes #39924 from cloud-fan/minor.
