actions: improve error messages and reenable error related tests

[DanielMSchmidt]

We disabled a few tests around error handling for actions when we refactored the way actions work in #37444. This PR re-enables them albeit differently: Instead of adding context for how to proceed (undo changes, retry failing / not-yet-run actions) we show the invocation of the action. This gives the user more context. We will wait for user feedback if the next steps would be useful as well even with this context already in place. It is a bit more difficult to add this info in the current system therefore we postpone it for now until the work is more stable.
