Display Initializing project... message when initializing project (#6661

)

The current `"Project Name Uninitialized"` seems a bit scary. Why not display text describing what's really happening?

![Initializing project...](https://github.com/enso-org/enso/assets/26887752/b852ccdc-b1e4-4d3d-aa40-9e23e18ef43c)

Isn't `Initializing project...` better?
