Add Solid documentation and SolidStart implementation

[davedbase]

Summary

Augmenting documentation and implementation for URQL + Solid.

Set of changes

1. Documentation for the Solid implementation was not added to the URQL docs site.
2. Contributes a SolidStart implementation which is Solid's meta-framework that uses more powerful primitives.
3. Switches utilities to use Solid Primitives utilities which is great for DRYing up some minor code.

Todo

• Ensure all tests and linters are passing
• Soliciting feedback from Solid community
• Review final documentation details

This is ready for publishing. I'll adjust the local linked files in the examples just before publishing. Just let me know when this is ready to go up :)

Edit: sorry squeezed in a last minute adjustment. Mutations were handled incorrectly.

@JoviDeCroock CI is now fixed :)

@JoviDeCroock apologies for the package versioning mistake. I did read the contribution guide but neglected to undo the package version bumps. Let me know if there's anything else I can support on.

You need to add changesets as detailed in our contributing guide, after that we should be good to go. It won't auto-publish as it's a net new package so I'll have to do that on the weekend (run pnpm changeset)

Ah I see what you mean @JoviDeCroock. I neglected to read adding-a-changeset.md. I've pushed two change sets, one will publish a minor release for the @urql/solid-start package and the other a patch for @urql/solid.

I had previously added those manually to the CHANGELOG.md of each package, but according to the details in the documentation this change set process will append it for me. I've hence moved my manual changes to that file so that the changeset can do its thing.

I believe we're good to go now.
