Running aspire init in empty folder fails

[jmezach]

Is there an existing issue for this?

Describe the bug

When running aspire init in an empty folder I get an error that it would overwrite existing files (see output below). I believe this is because the initial language choice creates an aspire.config.json and then the scaffolding of the actual project tries to create the same file again, resulting in the error.

Expected Behavior

I would not expect getting an error.

Steps To Reproduce

mkdir repro
cd repro
aspire init

Choose C#
Get the error above
