Fix and update benchmark notebooks to getml 1.5.0

[cyclux]

• Upgraded getml to version 1.5.0.
• Added Colab Badge:
  • Included a Colab badge for easy access.
  • Applied the remove_cell_on_docs tag to hide the badge in MkDocs documentation.
• Fixed getml.engine.launch() issue:
  • Removed home_directory=Path.home() to avoid compatibility issues in certain environments.
  • Tested in both native and Docker environments.
• Improved Colab Compatibility:
  • Added automatic download of the utils folder to ensure the notebook is fully self-contained and runnable in Colab.
• Updated Headers:
  • Adjusted H1, H2 etc. headers to align with MkDocs' table of contents (ToC) hierarchy requirements.
• Fixed deprecation warnings of pandas:
  • Added ignore FutureWarning to utils class in ft_time_series_builder.py
  • This is a temporary fix, the class needs an update to cast the types correctly
