Doc: use "unnumbered" footnotes (GH-98954)
Use unnumbered footnote in this file to avoid reseting the footnotes numbering.
Example: when building the tutorial into a PDF and using `latex_show_urls = "footnotes"`; this footnote become the number 8. However, without this change, the footnote shows the number 1.
