Add debugging to windows release action

[galt-tr]

This pull request enhances the Windows release workflow in .github/workflows/release.yml by improving the setup and verification steps for code signing. The changes ensure that the correct tools are available in the environment and provide better diagnostics for certificate access and signing operations.

Windows code signing workflow improvements:

• Added a step to dynamically locate and add the directory containing signtool.exe to the PATH on Windows runners, ensuring the signing tool is always available.
• Added a step to verify DigiCert certificate access using smctl keypair ls, providing early feedback if there are issues with certificate availability.
• Enhanced the signing step to output a message before signing each .exe and enabled verbose output for better troubleshooting.
• Updated the signature verification step to call signtool directly from the PATH, relying on the earlier step that adds it to the environment.
