Preview component has Error if we use @ubeac/svelte package in other projects

[TheHadiAhmadi]

Preview component depends on 'prismjs' and 'prism-svelte' packages.

I have error from 'prism-svelte' which says Prism object is not defined.

@pournasserian what do you think if we remove Preview from npm package?

Preview is used only in our documentation site, and most of projects will not need this.
