Added Server 2025 to Windows version constants

[smashery]

This adds the version constants for Windows Server 2025.

Verification

• Spin up a Server 2025 instance (I tested on AWS)
• Start msfconsole
• Obtain a meterpreter session on it
• Use a module with the WindowsVersion mixin; e.g.:
• use windows/local/cve_2020_0787_bits_arbitrary_file_move
• set session 1
• irb
• version = get_version_info_impl
• version.product_name
• Verify that it says Windows Server 2025
