Disabled Nx native command runner for the build artifacts job

[9larsons]

no ref

The Build & Publish Artifacts job's Build server and admin assets step has intermittently segfaulted before Nx starts the target script — nx run ghost:build:tsc is killed with SIGSEGV roughly a second in, before Nx or tsc produce any output (e.g. run #49431).

This sets NX_NATIVE_COMMAND_RUNNER: "false" on that step's env, which keeps Nx orchestration and caching but avoids its native PTY command runner. It mirrors the same fix already applied to the acceptance test job in 2798ba3; there it lives at the job level because that job already had a job-level env: block, whereas here the failing step already carries its own env:, so scoping it to that step keeps it targeted to the exact command that crashes.

Walkthrough

This change modifies the CI workflow configuration file to add an environment variable, NX_NATIVE_COMMAND_RUNNER: "false", to the "Build server and admin assets" step within the job_build_artifacts job. This setting disables Nx's native PTY runner for that specific step, along with accompanying explanatory comments. No exported or public entities were altered.

Possibly related PRs

• TryGhost/Ghost#28843: Both PRs modify the same CI workflow file around Nx-related CI behavior.
• TryGhost/Ghost#29154: Applies the same NX_NATIVE_COMMAND_RUNNER="false" fix to address Nx native runner segfaults, but for the acceptance tests job instead of job_build_artifacts.
