PR Review: Fix gpu integ test failure due to outdated MPG

• Read PR diff
• Review the change for correctness & conventions

Summary

The change updates the PROD account (729646638167) model_package_group ARN in the integ test config from openai-reasoning-gpt-oss-20b-mtrl-mpg to mock-oss-test-mtrl-mpg.

This looks correct and is consistent with the surrounding PROD config, which already uses the mock-oss-test naming for base_model ("mock-oss-test") and existing_job_name ("mock-oss-test-mtrl-..."). The old MPG name referenced openai-reasoning-gpt-oss-20b, which no longer matches the model actually used in that account — so this alignment fixes the outdated reference.

No correctness, security, or best-practice concerns. It's a test-fixture value update only, with no impact on public SDK interfaces or consumers.

One minor observation (non-blocking): the BETA account config at line 85 still uses the old openai-reasoning-gpt-oss-20b-mtrl-mpg MPG name while its base_model is "mock-oss-test". If BETA is affected by the same drift, it may need a similar update — but that's out of scope for this PR and only worth checking if the BETA suite is failing too.

LGTM. ✅

Non-blocking observation

The BETA account config (742774200982, line 85) still uses openai-reasoning-gpt-oss-20b-mtrl-mpg while its base_model is "mock-oss-test" — the same drift this PR fixes for PROD. If the BETA suite hits the same MPG failure, it may need a similar update. Out of scope for this PR, only worth checking if BETA is also failing.

LGTM. ✅
