[CI] Fix NuGet restore: use Liara mirror (Nexus TLS chain incomplete)

mirror.soroushasadi.com serves a leaf-only TLS chain (no intermediate).
.NET on Linux does not auto-fetch the intermediate via AIA like Windows
does, so CI/Docker restores fail with NU1301 PartialChain. Switch the
Linux build configs (CI inline config + nuget.docker.config) to the
Liara mirror, which serves a complete chain. Also disable NuGetAudit to
avoid the api.nuget.org (filtered) 100s timeout + NU1900 noise.

Local dev nuget.config keeps Nexus primary (Windows resolves the chain).
Re-add Nexus to the Linux configs once nginx serves fullchain.pem.
