Add SolidJS Example and Integrate SolidJS into Documentation

[pravintargaryen]

Hi @DanWahlin,

This pull request adds a SolidJS example and updates the documentation to include SolidJS integration guidance.

What’s included

• Added a working example demonstrating usage with SolidJS
• Updated docs to mention SolidJS alongside existing frameworks
• Clarified setup and usage patterns specific to SolidJS
• Ensured consistency with current documentation structure

Why this change
SolidJS is gaining adoption due to its fine-grained reactivity and performance. Including an example and docs support makes it easier for SolidJS developers to onboard and use the project effectively.

Hi @pravintargaryen. Having a SolidJS example in the "samples" folder as well as info in the README would be nice to have. If you want to submit a sample that's similar to one of the existing Angular ones that'd be great. I just did a big refactor on the full project (v3 was published) so if you wanted to update the PR with the latest version and then include that sample, update to the readme, etc. that would be great.

Sure @DanWahlin

Hi @DanWahlin,

Apologies for the delay. I was traveling and couldn’t give this the attention it deserved. I’m back now and focusing on this full-time. You can expect the updated PR to align with v3 within this week.

Thanks for the refactor and guidance!

Hi @DanWahlin,

I've added two SolidJS applications to the samples folder, following the same structure as the existing Angular examples.

I'll submit another PR for the remaining two samples along with the updated README after you’ve had a chance to review this one.

Also, I’m considering extending the samples to include Lit and Qwik examples as well. Let me know if you’d be open to that.
