The trampolines are already updated in this PR – but also a good idea. Kicked off a dry-run build! https://github.com/prefix-dev/pixi/actions/runs/22399075772 |

The MSI is properly signed 🎉 and the same for the .exe

Description
This PR integrates signing for Windows, by using a certificate on Azure that is linked to us (prefix.dev GmbH). After signing, the binaries should not trigger a smart screen anymore when downloading (especially relevant for the MSI installer). Note: today, a smart screen is not triggered by the PowerShell script afaik.
We also use the same signing mechanism for the "trampoline" binaries on Windows (used by Pixi Global).
We do not yet sign the "launcher" binaries (ideally that would be done by the conda community in conda/conda-launchers#11).
