feat(dotnet): add ci-workflow generator

[Copilot]

Implements a ci-workflow generator for .NET projects, following the pattern established by the gradle ci-workflow generator.

Changes

• Generator implementation (packages/dotnet/src/generators/ci-workflow/)

  • Supports GitHub Actions and CircleCI
  • Configures .NET SDK 8.x
  • Uses linux-medium agent type for Nx Cloud task distribution
  • Includes Nx affected commands and self-healing CI (nx fix-ci)

• Templates

  • GitHub Actions: uses actions/setup-dotnet@v4
  • CircleCI: uses mcr.microsoft.com/dotnet/sdk:8.0 docker image

• Registration: Added to generators.json alongside existing init generator

Usage

# Generate GitHub Actions workflow
nx g @nx/dotnet:ci-workflow --ci=github

# Generate CircleCI workflow  
nx g @nx/dotnet:ci-workflow --ci=circleci

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• repo.gradle.org
• staging.nx.app

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Issue Title: Generate ci-workflow for .NET
Issue Description: This should be similar to the existing ci-workflow generator for gradle, reference https://github.com/nrwl/nx/tree/master/packages/gradle/src/generators/ci-workflow

The generator should be scaffolded using nx g generator ./packages/dotnet/src/generators/ci-workflow/ci-workflow

📋 I wasn't able to determine which GitHub repository to work in.

I think it's one of these, but can you tell me which one is right?
