fix(core): exec should not log usage info when inner command fails

[AgentEnder]

Current Behavior

When a command ran through nx exec fails, the output of nx exec --help is logged out twice.

Expected Behavior

Failing inner commands from nx exec should not log usage text.

agentender@DESKTOP-RFT62G1:~/nx$ npm run check-commit

> check-commit
> nx exec -- echo 'oh no'; exit 1

yarn run v1.22.19
$ /home/agentender/nx/node_modules/.bin/nx run '@nrwl/nx-source:"check-commit"'

> nx run @nrwl/nx-source:check-commit

$ nx exec -- echo 'oh no'; exit 1
oh no
