version 0.4.0 is missing types

[mat813]

The package.json still has "typings": "types/index.d.ts", but that file is not in the npm package, which leads to errors like this:

$ tsc                    
src/index.ts:1:52 - error TS7016: Could not find a declaration file for module '@oruga-ui/theme-bulma'. '/home/marnold/work/commun/bulma-ovea/node_modules/@oruga-ui/theme-bulma/dist/bulma.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/oruga-ui__theme-bulma` if it exists or add a new declaration (.d.ts) file containing `declare module '@oruga-ui/theme-bulma';`

1 import { bulmaConfig as originalBulmaConfig } from '@oruga-ui/theme-bulma';
