PR #5 rebase concatenated PR #5 env additions onto PR #7 env additions on
the base + sharedpos Deployments, producing duplicate-key validation
errors in ArgoCD's structured merge. The DOTNET_INSTALL_DIR and
NUGET_PACKAGES values are identical between PR #5 and PR #7; keep the
PR #7 originals and retain only the unique new env vars from PR #5
(DOTNET_CLI_TELEMETRY_OPTOUT, DOTNET_NOLOGO, DOTNET_GENERATE_ASPNET_CERTIFICATE).
No behavioral change — same final env var set, no duplicates.
