Retrive screenshot in relative path of current directory

In Rails engine `Rails.root `returns the path of the dummy application.
Therefore, there is no `tmp` directly where the test is running, so can
not get the screenshot.
For this reason, instead of directly specifying tmp, retrive screenshot by
relative path from the current directory.

Fixes #30405
