Increase jest timeout in CI

What does this MR do and why?

Since our update to node@20 we are seeing more flakiness in jest specs. This is due to timeouts of individual specs.

While we are seeing patterns of certain specs being slow because e.g. they do big async imports, it is kind of hard to debug exactly what is going on in CI. We have the suspicion that for example Garbage Collection or Disk IO of specs running in parallel might be at play here.

We are planning to create monitoring for the slowest specs and create issues so that they can be debugged without breaking master or blocking Merge Requests: #457179
