[Maintenance] Centralize prettier configuration

### Relevant component

refarch-tools

### Problem description (optional)

We already have `java-tools` so I suggest creating a new directory for `node-tools` and maintaining a package for the prettier configuration there.
Currently the prettier tooling is located in https://github.com/it-at-m/itm-prettier-codeformat, however I think it would be way more manageable if we could maintain all configurations in one place.

### Desired solution

Move content of https://github.com/it-at-m/itm-prettier-codeformat over to this repository and release under a new npm package name.
Also, set the old package to deprecated and link to the new one.

Start by comparing the existing java-tools layout with the itm-prettier-codeformat repository linked in the issue. Define the new node-tools package around the migrated Prettier configuration, then verify that it can be released under a new npm name and that the old package points users to it and is deprecated.
