Add support for dark mode

[mcruzdev]

It would be great to have a dark mode option for the documentation site. Many users prefer using dark themes for prolonged reading sessions, as it reduces eye strain and provides a more comfortable experience, especially in low-light environments.

The website is using mkdocs, so it should be easy to do (famous last words).

The main issue is pictures - they render poorly if the background changes.

[mcruzdev]

Really!

@cescoffier I would like to add a new connector for Dapr PubSub. But I am very very new on smallrye-messaging :) Could you help me with this, at least to review pull requests, etc?

[cescoffier]

@mcruzdev yes, we would need a bit of CSS to set a background for these images.

@mcruzdev About the new connector, sure! However, we tend to host them outside this repo (in Quarkiverse).
