Subject: [PATCH] Do not add `java.io.IO` import in
 `ReplaceSystemOutWithIOPrint`

Fixes #1115. JEP 512 moved the new `IO` class to `java.lang.IO` for the
final Java 25 release, so it is implicitly imported by every source file;
the `java.io.IO` location only existed in the preview JEPs 477 and 495.
Reverts the import added in #1093, which produced an import of the
non-existent `java.io.IO`.
