`es-module/test-typescript` timing out and failing on AIX on v25.x-staging

[richardlau]

es-module/test-typescript is persistently timing out and failing on v25.x-staging for AIX.

Refs: https://github.com/nodejs/reliability/blob/main/reports/2025-12-10.md (both PR's are against v25.x-staging)

e.g. https://ci.nodejs.org/job/node-test-commit-aix/60144/nodes=aix72-ppc64/consoleFull (v25.x-staging, eb0705a):

04:03:07 not ok 1093 es-module/test-typescript
04:03:07   ---
04:03:07   duration_ms: 120114.51500
04:03:07   severity: fail
04:03:07   exitcode: -15
04:03:07   stack: |-
04:03:07     timeout
04:03:07   ...

This has not been seen on either v24.x-staging or main.

bf27b85 is part of #60663. AFAIK we've not seen the es-module/test-typescript failures on main but they are persistent on v25.x-staging. Maybe due to the different version of V8?
