Code Review

This pull request adds a link to an introductory video in the 'Hot Topics' section. The change is functionally correct. I have provided one suggestion to improve the long-term maintainability of this documentation file by using an AsciiDoc attribute for the video ID.

[gemini-code-assist]

For better maintainability, consider defining the YouTube video ID as an AsciiDoc attribute at the top of the document and then referencing it here. This makes it easier to update the link in the future if the video changes, as the value is centralized in one place.

For example, you could add this at the beginning of the file:

:intro-video-id: Gz9sc6LkFT4

And then change this line to:

* https://youtu.be/{intro-video-id}[Watch "An Introduction to ArcadeDB"]

I am not in favor of adding this video link, especially not to the most prominent position in the docs.

IMHO anybody arriving at the docs needs specific info about ArcadeDB and not an ad.

I also have some quality issues with the video itself (if you want I can send those to you privately).
