Current State & Issue

At the moment, the Changelog of the Kipper language is kept track of in the Changelog tab of the website, where it is loaded from GitHub and then rendered in the browser of the user, before being shown.

This is unnecessary since the website should be built every time a new release is shipped, meaning that the changelog should always be up-to-date during the builds and there will never be important changes without a new release/build of the website.

Expected Changes & Improvements

• Move the build of the Changelog to the build-webpages.ts script, where the Changelog Markdown can be directly rendered to HTML and then statically shipped.
