fix: problems with [email protected] (#111)

The 4.0.0 release of the `marked` package contains a breaking change
that - guess what - breaks the <VueSimpleMDE> component. The main change
is that the `marked` package does NOT provide a default export anymore.

For more information please see the [release notes for
`[email protected]`](https://github.com/markedjs/marked/releases/tag/v4.0.0).
Also, you might be interested in a [related pull request inside the
SimpleMDE repo](sparksuite/simplemde-markdown-editor#825).
