Describe the bug

ProductVersion and FileVersion should be set in .exe at buildtime.
This affects version management and ability to find any vulnerable versions

Affected versions

Probably all, but verified with these gh --version
gh version 2.63.1 (2024-12-03)
https://github.com/cli/cli/releases/tag/v2.63.1

Steps to reproduce the behavior

Check details from explorer, or this in powershell:

[System.Diagnostics.FileVersionInfo]::GetVersionInfo("C:\Program Files\GitHub CLI\gh.exe")

Expected vs actual behavior

ProductVersion   FileVersion      FileName
