Mod proposals to Kroki post

According to earlier comment:

• try to reduce the hurdle for Gitlab non-natives using easier wording, some basic gitlab intro, link to actual gitlab examples.

To do:

• Easier intro text and links.
• Create Gitlab example project and link to it.
  • make that example public do this in parent branch kroki-post
• clarify post categories/types and show on front page ----> move to extra issue/MR

+## What is it about and where can it be applied?
+Gitlab is perfect for colloborative work on codes, scripts and other shared files.
+Now you can also create virtually all sorts of diagrams and sketches directly in Gitlab,
+both allowing to **quickly create plots**, as well as
+collaboratively build and maintain **complex graphs**.
+
+All graphs are built from simple scripts directly in Gitlab using a plugin named [Kroki](https://kroki.io/).
+Such scripts can be used in any place on the [Helmholtz-wide Gitlab](https://gitlab.hzdr.de)
