Fix broken example sandboxes

[markerikson]

Per https://www.reddit.com/r/reactjs/comments/yzcegz/when_using_redux_it_is_better_to_go_basic_than/ix0mxj3/?context=3 , the "Svelte" and "Conditional Fetching" examples appear to be busted. The "Conditional" one is breaking with an "invalid element type" error.

The sandboxes themselves are directly pointing to the relevant folders under https://github.com/reduxjs/redux-toolkit/tree/master/examples , so fixes should be applied to that code.

There is something funky going on with the embed code sandbox. This is my first time looking at these things so so far I can only point out at the weird things I see:

• Not reproducible locally (cloning repo, starting examples/query/react/conditional-fetching/)
• Not reproducible in these two following code sandbox links. That second URL seems to be the actual origin of the code and modules. Except something is out of sync, in the embed link in which this is reproducible.

When opening the Conditional Fetching docs, the invalid element type error occurs because the following file is running: https://vgmh2.csb.app/boilerplate-.tsx?$.ts? [sm] and is clearly code that's out of sync with the actual sandbox. The Pokemon import is expected to be default.

If you just add export default Pokemon that error fixes itself (even though it makes no sense according to the files in the sandbox), only for another error to show, it believes the App/Pokemon is not wrapped by the provider, along with the weird ReactDOM.render warning (also due to boilerplate-.tsx).

I don't know anything, but doesn't feel like it's due to the code in the repo...
