Update code signing with latest Azure Trusted Signing tools/tasks (gi…

…t-ecosystem#1644)

- Update to the latest version of the GitHub Action (the
`azure/azure-code-signing-action` action has been replaced by the
`azure/trusted-signing-action` one).

- Deploy a forked version of the `Sign.Cli` tool for Trusted Signing,
which includes the ability to export the certificate. The fork can be
found here https://github.com/mjcheetham/sign/tree/export-opt, and the
PR to submit this change upstream here
dotnet/sign#734.

With these changes we are now completely secret/credential free, and
rely on federation only.
