Update topics/ada.qmd

Changed this back to relative link including the path to the topics. Even though the relative path in the same folder works here, it wouldn't work if the topic were included in a guide.

 CLI and scripting skills are very useful to have for every researcher, but  if you feel you do not have the time to learn these skills there might be other options available such as [the VU Compute Hub](https://hub.compute.vu.nl) or [SURF Research Cloud](../topics/researchcloud.qmd) where you can run some graphical tools.
 
 ### GPUs in ADA
-Some workloads, such as Machine Learning, require a GPU. At the moment only some of the compute nodes in the ADA community partition have GPUs, the availability is not sufficient for everyone at any given time. If your workload requires more extensive use of GPUs and your department has no dedicated compute nodes with GPUs, you can apply for access to the national HPC infrastructure [Snellius](./snellius.qmd) or consider [buying ADA compute nodes](#buying-dedicated-compute-nodes) with GPUs for your department.
