[FEAT] Add prettier dev formatting

[m10rten]

Using a standard prettier config, the entire codebase will be in sync.

• creates a .prettierrc.json
• installs prettier as dev dependency
• adds a settings.json file in the .vscode folder to ensure everyone that uses vscode has the formatOnSave setting on true and the prettier module path to the node modules so the same prettier version is used.
