[CI] UrlDecodeTests class failing (#135308)

- Change the expected error message for bad decoder input test cases depending on the JDK version.
- Prior to JDK25, the exception message is
 `Illegal hex characters in escape (%) pattern - Error at index 0 in ...` but it has changed to
 `Illegal hex characters in escape (%) pattern - not a hexadecimal digit ...`.
