ACTVTNS-623 Update @segment/action-emitters to 1.3.8

[kkolhe-twilio]

Summary

Updates @segment/action-emitters package from v1.3.6 to v1.3.8 to support Entity Data Freshness feature.

What's new in v1.3.8:

• Adds warehouse_entity_values_changed_track trigger - fires when entity property values change
• Adds warehouse_all_triggers_track trigger - combined trigger for entity add/remove/change events
• Adds journeys_step_all_triggers_track trigger - journey step enter/exit combined trigger -- This is owned by journey's team was already in the packaged

Why needed:
Control Plane must recognize and validate these new trigger types when they're used in activations. Without this update, the new triggers would be rejected during activation creation.

Downstream impact:

• Frontend (app repo) also needs to update to v1.3.8
• Compute team implementing backend detection logic (separate effort)

---

🧪 Testing

• 🚫 Testing not required because its a package update and merged in stage and it looks good in stage

🔧 Test Plan

• Merged to stage and allowed to run for >= 4 hours.
