Export the plugin name

[r13v]

The typescript-plugin-css-modules rely on the plugin name to distinguish the plugins to load. It will omit the postcss-nested plugin without the exported postcssPlugin. Therefore, the IDE does not have intelligence for the nested selectors.

According to PostCSS types it is a correct API:

 export interface PluginCreator<PluginOptions> {
    (opts?: PluginOptions): Plugin | Processor
    postcss: true
  }

Maybe we need to fix typescript-plugin-css-modules? Or you can add () after plugin in your config as a quick fix.

@ai Sorry, my bad. The postcssPlugin property should be defined in the plugin creator like the postcss-mixins do.

No, the current API is correct. Seems like we have typescript-plugin-css-modules issue.
