fix: invalid JS in README

[marvinhagemeister]

There is no import { Foo as default } from ".." in JS. default cannot be used there as a keyword.

This works fine in SaaSKit: https://github.com/denoland/saaskit/blob/5e13b39496e90c3df9ab49465ce80fcb878a792c/islands/Chart.tsx

@iuioiua It does work in SaaSKit because it's using an export statement instead of an import statement. The foo as default syntax is perfectly fine with export statements. But in the README it's used as part of an import statement and that's not valid JavaScript.

Oh, I see. In that case, since the problematic LOC is in an island, should the example then be this:

- import { Chart as default } from "$fresh_charts/island.tsx";
+ export { Chart as default } from "$fresh_charts/island.tsx";
