5d4101a1 - Remove dangling references to deleted WebGPU Python packaging pipeline

Remove dangling references to deleted WebGPU Python packaging pipeline The WebGPU Python packaging pipeline YAMLs were removed (superseded by the WebGPU plugin EP), but the release orchestrator still referenced pipeline 2107: - Remove the webgpu_python_packaging parameter from main-release-pipeline.yml - Remove the PipelineConfig(id=2107) entry from trigger_and_wait_pipelines.py Also fix backslash paths in skill-file citations to .github/workflows/linux_webgpu.yml.
