fixes #1455

We need to be careful bumping this. Many packages rely on source-map in one form of the other, and the beta version is used far less, which might lead to version resolution problems in some projects/with some packages.
Why does bumping the version fix the bug? Could we fix it in a different way?
Edit: I guess it's mozilla/source-map#349 and we can't fix that from the outside. More people will run into this in the long run, so yeah maybe we should bump the version.

Edit 2: I discovered https://github.com/jridgewell/trace-mapping, which is a drop-in-replacement (same API) for source-map which is lighter, faster, no WASN, sync, maintained -> we should switch to that.
