TUN-9800: Migrate apt internal builds to Gitlab

* TUN-9863: Introduce Code Signing for Windows Builds

This commit adds a signing step to the build script for windows binaries.
Since we package the MSI on Linux, this commit adds another CI step that depends on package-windows and signs all of the windows packages.

To do so, we use azuresigntool which relies on a certificate stored in Azure Vault.

Closes TUN-9863

+    <strong>We have rolled our public key for package signing.</strong> If you are using RPM-based distributions (RHEL,
+    CentOS, Amazon Linux, etc.) or Debian Trixie and have the old key installed, RPM/Deb packages will no longer work with the old key.
+    Please update your repository configuration using the instructions below to ensure you can continue receiving
+    package updates. The previous keys will still work for other distributions for the time being, but it is now DEPRECATED and will be removed on 30 April 2026
