Update deprecated /workinggroups/ links to /activities/

Working groups were renamed to activities. While redirects exist for backward compatibility, updating these links ensures consistency and reduces redirect overhead.

 Importantly, the group needed to agree on a definition of “conditions data”, concluding that in the context of large scale NHEP computing challenges it is the subset of non-event data used in event-data processing, often using distributed computing resources.

 ## Description
 
-There is a large number of training resources for newcomers in the field of High Energy Physics. The [HSF Training group](https://hepsoftwarefoundation.org/workinggroups/training.html) together with [IRIS-HEP](https://iris-hep.org/) has started to compile a curriculum of such training modules that helps to get beginners up to speed quickly. However, the [current listing](https://hepsoftwarefoundation.org/training/curriculum.html) in the form of a static table is quickly becoming overwhelming, and we cannot include many resources because of space limitations.

The [HSF Training group](https://hepsoftwarefoundation.org/activities/training.html) together with [IRIS-HEP](https://iris-hep.org/) has started to compile a curriculum of such training modules that helps to get beginners up to speed quickly. However, the [current listing](https://hepsoftwarefoundation.org/training/curriculum.html) in the form of a static table is quickly becoming overwhelming, and we cannot include many resources because of space limitations.
 This project is about creating a new training center that turns the static page into a dynamic list of training content that can be filtered by attributes such as programming language, common tasks, type of training, HEP experiment, etc. The candidate can start with the code of <https://learn.astropy.org/> (an unrelated training website of a popular astrophysics package) and change the underlying data sources: rather than being based on a series of Jupyter notebooks, configuration files should allow listing arbitrary content.
