Add libstdc++-12-dev for linux (#12962)

Release Notes:

- N/A

PS: 👋 Congrats on the release 🎊 and hey from
discussing CRDTs at the [GitPod/DevX conference last
year](https://www.youtube.com/watch?v=wXT73bBr83s)! Just read the [blog
post](https://zed.dev/blog/zed-decoded-linux-when) and thought I'd
finally try zed out (I have a linux laptop). This was the only snag I
ran into 👏
