Introducing Argilla Guru on Gurubase.io (#5608)

Hello team,

I'm the maintainer of [Anteon](https://github.com/getanteon/anteon). We
have created Gurubase.io with the mission of building a centralized,
open-source tool-focused knowledge base. Essentially, each "guru" is
equipped with custom knowledge to answer user questions based on
collected data related to that tool.

I wanted to update you that I've manually added the [Argilla
Guru](https://gurubase.io/g/argilla) to Gurubase. Argilla Guru uses the
data from this repo and data from the
[docs](https://docs.argilla.io/latest/) to answer questions by
leveraging the LLM.

In this PR, I showcased the "Argilla Guru" badge, which highlights that
Argilla now has an AI assistant available to help users with their
questions. Please let me know your thoughts on this contribution.

Additionally, if you want me to disable Argilla Guru in Gurubase, just
let me know that's totally fine.
