Fix: Enable exception mode to skip scripts on first error

[glensc]

Replaces #1254

Noticed that "danger:prepush" ran commands with ";" rather "&&" meaning the next command is still executed if the previous one failed. This resulted in very weird errors due to the previous step failure.

Now, aborts of first error:

➜ yarn danger:prepush
yarn run v1.22.17
$ set -e; yarn build:fast; yarn test:fixtures; node distribution/commands/danger.js local --base main --dangerfile dangerfile.lite.ts
$ tsc -p tsconfig.production.json
source/commands/ci/runner.ts:70:30 - error TS2339: Property 'publishCheck' does not exist on type 'SharedCLI'.
...
➜

I'm wary about this breaking on Windows - have you tried it there? The CI doesn't look to be running any of these commands

Using "; " separator is not new. Some scripts already used those. And I do not have any windows platform access.

Same problem in other projects in this organization:
