Remove placeholder text from FineTuning_Scenarios.md documentation

[Copilot]

Editor placeholder text was rendering in published documentation across all language versions.

Changes

• Removed placeholder lines from md/03.FineTuning/FineTuning_Scenarios.md and 10 translation files:
  • English: [Insert icons for ONNX Runtime and ONNX Runtime]
  • Japanese: [ONNX Runtimeのアイコンを挿入]
  • Spanish: [Insertar íconos para ONNX Runtime y ONNX Runtime]
  • Plus Arabic, Urdu, Punjabi, Myanmar, Serbian, Tagalog, and Pidgin equivalents

The preceding sentence "Let me show you the icons for each of these technologies" provides sufficient context.

@leestott
I noticed that beyond the placeholder text issue, the Tools & Framework section might still benefit from some clarification particularly around the duplicated ONNX Runtime reference and overall consistency.

If you're open to it, I'd be happy to take a pass at refining the overall structure and consistency of the document.
