The only updates are package versioning, most importantly:
brax 0.8.3 -> 0.12.1
gymnasium 0.27 -> 0.29
configspace 0.7 -> 1.2
This required some minor changes in different parts of CARL, but from the user side, they are basically irrelevant. The configspace update slightly changed the interface for normally distributed context, but this is reflected in the examples.
