ci(rest): pin resource-push-ngc to arm64-capable NGC CLI (#2875)

## What
Pin `resource-push-ngc` to NVIDIA/dsx-github-actions@ae74448 (merged) —
the version that downloads the **arm64** NGC CLI on arm64 runners.

## Why
After the native per-arch REST build landed, arm64 build legs failed at
`Upload binary artifact`: the old action installs the x86_64 NGC CLI →
`cannot execute binary file: Exec format error` on arm64 runners.
dsx-github-actions#51 fixes it (verified on amd64 + arm64 by its own
self-hosted test job); this bumps all 4 pinned refs to the merged SHA.

## Verify
NGC uploads are push-only, so they run on `main` (not PRs). After merge,
the first `main` REST build should have all arm64 legs green (binary
upload included) and the `merge` job run for the first time.
