Open Release Notes and Credits in dialogs

For this to work as it should, we need to create json files for the dialogs and make a request via the fetch API. Will need to play around styling too.

Do not forget to delete the old html files once done.

To attempt this using HTML template element.

To follow the same concept for release notes. Structure may be as follows:

interface Version {
title: string;
changes: Array<Change>;
}

interface Change {
text: string
changes: Array<SubChange>;
}

interface SubChange {
text: string;
}

To do:

1. Link the new changelog method to the version link.
2. Decide and implement layout for Credits and Version links.
3. Move all changelogs to the new Typescript file (dialog).
