    Do the new graph versions work for you?

    @robinje @kangkang333 Interesting that this isn't being catched by the tests, but I would need a more detailed description to reproduce this error. Doesn't v0.23.0 work either?

    import (
   dbgraph "github.com/dominikbraun/graph"
)
type Template struct {
   dbg    dbgraph.Graph
}
func (t *Template) DBGraph() {
   t.dbg = dbgraph.New(dbgraph.StringHash, dbgraph.Directed(), dbgraph.PreventCycles())
}

    Error on build: cannot use generic type graph.Graph[K comparable, T any] without instantiation. I think this is the same problem as reported by @kangkang333. Using Go V1.21.
