Absolute internal references instead of relative ones

[soxofaan]

I noticed there are quite a lot of internal references in the markdown files using absolute https://documentation.dataspace.copernicus.eu/... links instead of proper relative internal references (e.g. [registration](../../../Registration.qmd)).

This makes the docs brittle, you don't get build-time warnings/errors about broken references, and makes it confusing to test non-production builds of the docs.

examples I found:
