Format TypeScript/JavaScript files

[PhilippGackstatter]

Description of change

Format TypeScript and JavaScript files with dprint by adding a new plugin. This should integrate nicely with our existing CI infrastructure and the formatting we already do on machines locally.

The configuration is the plugin's default, except for indentWidth = 4 and arrayExpression.preferHanging to match what we already use mostly. The config and its defaults can be found here, in case we want to customize more things: https://dprint.dev/plugins/typescript/config/.

The idea is to format all js and ts files by default, but excluding certain directories like node_modules or target, which should ensure that directories added in the future should automatically opt-in to formatting.
