Getting Started improvement

[devtobi]

I have the following suggestions for the current getting started guide:

1. Instead of integrating the external css file via ´style´-Tag, use the @import url() variant.

@import url("https://assets.muenchen.de/mde/1.0.7/css/muenchende-style.css");
@import "@muenchen/muc-patternlab-vue/assets/css/custom-style.css";
@import "@muenchen/muc-patternlab-vue/style.css";

I tested this and it keeps loading the css dynamically and does not increase the bundle size.

2. Add additional information for the development setup in the context of using the library with web components:

<link
      href="https://assets.muenchen.de/mde/1.0.7/css/muenchende-fontfaces.css"
      rel="stylesheet"
/>

must be added to index.html to make sure the fonts are loaded when developing locally.
