Create cm catalog 01

[lujzi05]

There is a TODO in generate_links_to_querysets.py:

• The GITHUB_URL should be changed to 'https://github.com/prio-data/viewsforecasting/blob/main/' when merged to the main branch.
• Accordingly, adjusting the branch in the workflow update_views_pipeline_cm_catalog.yml is needed when merged.

So, let's go!
