fix(cli): change sh to bash in dockerCoreFetchCommand/dockerCoreJson

Both functions use 'set -euo pipefail' in the script passed to
'docker exec ... sh -lc', but /bin/sh on Debian (dash) does not support
-o pipefail, causing all microservice proxy and e2e API calls to fail
with 'sh: 1: set: Illegal option -o pipefail'.

Fix: use bash instead of sh, since bash is available in the container.
