improve logs for non existing project in the project-dependencies file

```
./bin/build-chain-cli.js -df 'https://raw.githubusercontent.com/${GROUP:kiegroup}/kogito-pipelines/${BRANCH:main}/.ci/pull-request-config.yaml' build branch -sp danielezonca/kogito-runtimes -p danielezonca/kogito-runtimes -b configure-windows-runtime-build
```
either `Printing local execution command` and error message have to be improved

real error: `danielezonca/kogito-runtimes` does not exist in the project-dependencies list. And the printed error is a technical one.

Start with bin/build-chain-cli.js and trace the build branch handling for a project missing from the project-dependencies list. Review how the local execution command and resulting error are printed; done means the missing project produces a clear user-facing message instead of the technical error.
