test: bump shared tests to pin the utf-16 single-error flush

common-runtime-tests-app 364cba6 asserts that a stream ending with both
a pending lead surrogate and an odd trailing byte decodes to a single
U+FFFD — the WHATWG end-of-queue step clears both pending states with
one error, as Node 24 (full ICU) also does. Matches ios#448 b5310e70.
