Introducing Connexion Guru on Gurubase.io (#1989)

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 [Connexion
Guru](https://gurubase.io/g/connexion) to Gurubase. Connexion Guru uses
the data from this repo and data from the
[docs](https://connexion.readthedocs.io/en/latest/) to answer questions
by leveraging the LLM.

In this PR, I showcased the "Connexion Guru", which highlights that
Connexion 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 Connexion Guru in Gurubase, just
let me know that's totally fine.
