feat(platforms): rename 'Network' platform to 'Network Devices'

BREAKING CHANGE: Update supportedMitrePlatforms to use 'Network Devices'
instead of 'Network' and bump ATTACK_SPEC_VERSION from 3.2.0 to 4.0.0.

- This change affects all objects using the x_mitre_platforms field
- Any data still using 'Network' will fail validation
- Version bump reflects the compatibility impact

This change aligns platform naming with current terminology standards and improves clarity,
but requires updates to existing data that references the 'Network' platform.
