Feature Request: Install a terminal addon in Capella images

[Wuestengecko]

The Git integration in Capella works quite well as long as it does, but as soon as it stops working for whatever reason, it tends to become utterly useless. In these cases, manual intervention through a terminal / shell is often required. One frequent reason for ("soft") breakage is failing pre-commit hooks: As you well know, the Git integration in Capella only shows a blank error popup in this case, without any option to see the hook output. However, there are also a few other situations where a terminal is needed or at least would be faster (if you know what you're doing).

It would be very convenient to have a terminal ready right inside Capella, without having to resort to opening a separate Jupyter session or logging into the Kubernetes backend.

As far as I could find out, the terminal addon installed in Eclipse-based IDEs is called "TM Terminal" - if we decide on adding a terminal at all, we should use that one, because it's already widely used.
