🐛 Handle project name initialization for current directory

Problem: currently, users cannot run fastapi-new in the current directory:

➜ uvx fastapi-new .
Installed 10 packages in 23ms

   FastAPI   Creating a new project 🚀

     error   Error: Directory '.' already exists.

Now: both fastapi-new (with no argument) and fastapi-new . work correctly to initialize a project in the current directory.
