Automatic update from web-platform-tests Replace assert_precondition with assert_equals in native-io/ (#23023) assert_precondition is deprecated (see https://github.com/web-platform-tests/rfcs/blob/master/rfcs/assert_precondition_rename.md). The usage in these tests was to check equality rather than whether a feature was supported, so replace with assert_equals. -- wpt-commits: 9b5bdedc2ad7797a6b99895157aeaa2b3a2d61e6 wpt-pr: 23023
