[Maintenance] Parallelization of npm jobs

[devtobi]

Relevant template

refarch-frontend, refarch-webcomponent

Problem description (optional)

Currently for our custom npm jobs defined in package.json we sequentially execute the steps (like prettier, ESLint, vue-tsc etc.).
This also means that follow up jobs fail if the previous one failed.
This hides important information about the result of a job (e.g. prettier fails and we don't know if ESLint would as well or not)

Desired solution

By using parallel execution of steps (e.g. with a package like https://github.com/open-cli-tools/concurrently) we can execute e.g. the linting steps in parallel and transparently show which part of the tooling failed.
The tool waits until all defined jobs where run and then aggregates into a final status code.
This way we give more transparency to the developer and increase the execution speed of linting (and potentially other stuff) on local machines and in CI/CD.
