[vite] `exports` order incorrect for vite

[waynevanson]

Hey there!

I'm using this preset in the vite config's rollupOptions, and receive the following warning from vite when running vite build after following the instructions from print instructions.

Screenshot of error message

Export from `rollup-preset-solid`

".": {
     "solid": "./dist/source/index.jsx",
     "import": "./dist/esm/index.js",
     "browser": "./dist/esm/index.js",
     "require": "./dist/esm/index.js",
     "node": "./dist/esm/index.js"
   }

Exports that remove the warning

".": {
      "solid": "./dist/source/index.jsx",
      "node": "./dist/esm/index.js",
      "browser": "./dist/esm/index.js",
      "import": "./dist/esm/index.js",
      "require": "./dist/esm/index.js"
    }

We should change presets to use the latter.

Would you accept this as an issue? If so I can create a PR.

This preset is awesome, thank you!
