set correct version for 'core' package (#219)

This PR uses `foreignObject` with CSS line-clamp to let the browser
handle text wrapping natively instead of manually wrapping on the
server. This provides better font-aware wrapping while keeping
server-side line estimation for SVG height calculation.

Fixes https://github.com/anuraghazra/github-readme-stats/issues/4862.

 To set up the project GitHub-Stats-Extended locally, run the following commands:
 
 ```bash
-./vercel-preparation.sh
 pnpm install
-pnpm --filter frontend run build
+pnpm run build:packages
+pnpm run dev:frontend
 ```
 
 The easiest way to run and test the project is to deploy it to Vercel as described in the [deployment guide](../docs/deploy.md).

 GitHub-Stats-Extended proactively precomputes and caches cards. This solves the problem where [cards wouldn't load on the first try](https://github.com/anuraghazra/github-readme-stats/issues/2603). It also gives GitHub-Stats-Extended more time while generating cards in the background, which allows it to fetch more repo data:
 
+### Customization of top languages card

 ### Multi-page fetching for accurate star counts

+So I decided to implement some of the highly requested features and make the enhanced project available to everyone. Since the initial release of this fork I have been in contact with the maintainers of [github-readme-stats](https://github.com/anuraghazra/github-readme-stats) and we decided to join forces. github-stats-extended is now in the process of becoming the successor of github-readme-stats.
-
-## Upstream Sync Strategy
-
-The maintainers of [github-readme-stats](https://github.com/anuraghazra/github-readme-stats) keep their project up to date with dependency upgrades and do occasionally merge some pull requests. I regularly merge the latest upstream changes into this fork to keep it in sync with the upstream repo.
-
-I also try to structure my own changes in a way that minimizes merge conflicts with the upstream repo. So some of my changes might even be merged back into [github-readme-stats](https://github.com/anuraghazra/github-readme-stats) if the upstream maintainers are interested.
 
 ## Compatibility Notes
 
+If there should be any changes in github-readme-stats in the future, they will be synced into this fork.
+
 GitHub-Stats-Extended aims to be fully compatible with [github-readme-stats](https://github.com/anuraghazra/github-readme-stats). Generally, additional functionality introduced in this fork has to be explicitly enabled via some parameter.
 
 So you can change an existing stats card url from [github-readme-stats](https://github.com/anuraghazra/github-readme-stats) to GitHub-Stats-Extended simply by changing the domain from `github-readme-stats.vercel.app` to `github-stats-extended.vercel.app`. The card will look the same.
