Rename to sobek

See grafana/k6#3772 Apart from renaming: 1. Drop the goja package as it depends on goja_nodejs and we are not forking this ... yet. 2. Drop references to goja_nodejs for the same reason. 3. Point out this is a fork of goja. Some links to goja are left as they link to issues that are still relevant for the point being made.

 setTimeout() assumes concurrent execution of code which requires an execution

 a pointer to the same struct). This includes circular objects and makes it possible to export them.
