[backports-release-1.11] Fix namespace of `IOError` in `random_seed` (#59689)
This PR addresses an issue with `IOError` not being exported from `Base`
and therefore being unavailable within `Random` if not fully qualified.
I'm not entirely certain which branch to make this PR to: `release-1.11`
or `backports-release-1.11`. Please change the target branch to the
appropriate one if necessary.
