Fix Docker build and remove .NET 8 build jobs

- Added Microsoft.Health.Fhir.Ignixa project to Dockerfile for proper restore
- Removed Linux_dotnet8 build jobs from pr-pipeline.yml and ci-pipeline.yml
- Updated .vsts-PRInternalChecks-azureBuild-pipeline.yml to use net9.0
- Updated SDK version to 9.0.308 in global.json

These changes are needed to complete the migration to .NET 9.0-only and
ensure the Ignixa SDK integration works correctly in CI/CD pipelines.
