docs: update GitHub Actions versions in documentation examples

[frigini]

Updates workflow examples in documentation to reflect actual versions after Dependabot PRs #22-24.

Changes

actions/checkout: v4 → v6

• .github/actions/validate-coverage/README.md (3 examples)
• docs/ci-cd.md (6 examples)
• docs/roadmap.md (1 example)

actions/setup-dotnet: v3/v4 → v5

• docs/ci-cd.md (2 examples)
• docs/roadmap.md (1 example)

Context

After merging Dependabot PRs that updated GitHub Actions to their latest versions, the documentation examples were still showing old versions. This PR synchronizes the documentation with the actual workflow files.

docs/roadmap.md (1)

660-660: ✅ GitHub Actions versions updated correctly in documentation examples.

The workflow example under Sprint 2 correctly reflects the updated action versions (checkout@v6, setup-dotnet@v5). These align with the Dependabot updates referenced in the PR and are consistent with industry standards.

Also applies to: 663-663

.github/actions/validate-coverage/README.md (1)

144-144: ✅ All three workflow examples consistently updated to actions/checkout@v6.

The documentation examples properly reflect the checkout action upgrade across development, release, and nightly build workflows. The consistency across all three examples provides clear, up-to-date guidance for users of this reusable action.

Also applies to: 169-169, 194-194

docs/ci-cd.md (1)

432-432: ✅ All GitHub Actions versions consistently updated across workflows.

The documentation examples in the CI/CD guide comprehensively reflect the action version upgrades:

• actions/checkout@v6 applied uniformly across all job workflows (build-and-test, security-scan, build-container, deploy-dev, deploy-production, PR Validation)
• actions/setup-dotnet@v5 applied consistently in dotnet setup steps

The systematic updates maintain documentation accuracy and provide users with correct best-practice examples.

Also applies to: 435-435, 459-459, 483-483, 519-519, 543-543, 573-573, 576-576
