When the docs examples tests run with `--cliSpecsConcurrency` greater than 1 (as happens on CI), the output of each process is [buffered][1] (to avoid interleaved output from multiple, parallel processes) and is only printed out once the process exits (either successfully or with an error). However, in cases where a process did not exit, the buffered output would be never printed out, thus making debugging the failure harder. This is the case, for example, if a build error happens during `ng e2e`. This can be seen in action in [this CI job][2], where the job fails due to no output, but the error (which is an incompatible TS version) is never printed out. To make debugging such situations easier in the future, this commit updates the `spawnExt()` helper to reject (causing the buffered output to be printed out) if there is no output from the spawned process for more than 5 minutes.
