test(web): update workspace-tabs-chrome assertion for logical margin (#5549)

The chrome-mirroring fix migrates .workspace-tabs-traffic from physical
margin-right to logical margin-inline-end so the traffic/window-controls
region mirrors under dir=rtl. Update the style-guard assertion to match
the new property name; the value (var(--app-chrome-traffic-margin)) is
unchanged.
