Add sourcemaps to sentry.io

[manuelmeister]

Error messages in sentry are only of limited use, because the source maps are not connected/linked.

Maybe we can solve this with this package:
https://github.com/ikenfin/vite-plugin-sentry

Or with the CLI: https://docs.sentry.io/platforms/javascript/sourcemaps/

Meanwhile there is an official package from sentry themselves:
https://github.com/getsentry/sentry-javascript-bundler-plugins/tree/main/packages/vite-plugin

I don't understand how to configure it, so it does not submit on every build (even locally) and how to inject version/commit hash, so it gets picked up.
