A few PR related to user-guide documentation

[Yelsin Sepulveda]

Hey everyone o/ I wanted to introduce myself, my name is Yelsin Sepulveda and I'm interested in applying to KubeVirt for GSoC 2026, specifically Project 3 (Component Testing Framework).

I've been working through the quickstart (Killercoda lab), Contributing and Getting Started docs, getting familiar with virtctl and the VirtualMachine CRDs, and have been lurking in the community meetings to get a feel for the codebase and culture.
Looking forward to getting more involved. Happy to jump into a good-first-issue on the testing side if there's something relevant - all good-first-issue look like they're being worked on. Besides that seeking any guidance or direction for getting started on this project.

Lastly, looking for reviewers for 2 small PRs related to user-guide that I put together. 

Thanks for your time!
