Ensure that the rollup-plugin-vue plugin is run before @rollup/plugin-typescript.

@Smashman, if use this order of plugins, then error changes:

	plugins: [
		alias({
			resolve: [ '.js', '.ts' ],
			entries: [
				{ find: 'vue', replacement: 'node_modules/vue/dist/vue.runtime.esm-browser.js' }
			]
		}),
		resolve(),
		Vue({ preprocessStyles: true }),
		typescript(),
		css({ output: 'dist/app.css' }),
	],

Error:

Error: Unexpected token (Note that you need plugins to import files that are not JavaScript)
    at error (.../vue3-rollup-bug/node_modules/rollup/dist/shared/rollup.js:5215:30)

Looks like typescript doesn't recognized at all.

Btw, see issue in typescript plugin (rollup/plugins#608), maybe this issue doesn't related to rollup-plugin-vue, because with rollup-plugin-typescript2 config from my reproduction works great.

@iassasin I had the same issue, switching from @rollup/plugin-typescript to rollup-plugin-typescript2 fixed it.

@kris-ellery, yes, I use this workaround too, but it's strange if it shouldn't work with official ts plugin.
