Improving Cross-Platform Signing Validation in Arcade's Post-Build Process

SignCheck has recently been updated to include verification for a variety of file types, including but not limited to: pkgs, deb, rpm, tar.gz, and others. However, due to limitations in tooling, these files cannot be consistently verified across all platforms and .NET versions. As a result, some file types can only be validated on specific platforms or .NET versions.

Currently, signing validation is an optional step in Arcade's post-build process, but it is only executed on Windows with .NET Framework. As a result, certain file types are being skipped in the validation process. To address this, I recommend updating the post-build template to run signing validation across all platforms and .NET versions.
