[Bug]: `jekyll new --blank` creates non-working scaffold due to sass naming

### Operating System

macOS 13.1

### Ruby Version

ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-darwin22]

### Jekyll Version

jekyll 4.3.1

### GitHub Pages Version

Latest

### Expected Behavior

After initializing a *blank* Jekyll scaffold using `jekyll new . --blank`, the resultant files generated should be directly compilable using `jekyll serve` with no errors.

This is expected behavior because the default option (generating using Minimal), `jekyll new .` creates a set of files that can be immediately run with `jekyll serve` and produce a working website scaffold on localhost with placeholder pages.

### Current Behavior

Currently, running `jekyll new . --blank`, then immediately `jekyll serve` without modifying any files results in the error:

```
Error: expected "{".
  ╷
4 │ @import "main";
  │               ^
  ╵
  /project_dir/assets/css/main.scss 4:15  @import
  /project_dir/assets/css/main.scss 1:9   root stylesheet 
  Conversion error: Jekyll::Converters::Scss encountered an error while converting 'assets/css/main.scss':
                    expected "{".
```

After much digging, it turns out this is due to a naming conflict of the `_sass/main.scss` and `assets/css/main.scss` files that were generated when running `jekyll new . --blank`, [as per this Stack Overflow question](https://stackoverflow.com/questions/38437416/jekyll-doesnt-compile-scss-files-with-jekyll-serve). The workaround is to rename either `_sass/main.scss` or `assets/css/main.scss` to a different name, e.g. `style.scss`.

That said, while the error persists on my machine, running it on other environments such as GitHub Pages yields no such error and the scaffold website compiles as expected. There doesn't appear to be anything wrong with my installation; to test the bug, I reinstalled Jekyll by the book based on the [official documentation](https://jekyllrb.com/docs/installation/).

To clarify, the bug is to do with the template files created by `jekyll new`. I know that of course it's easy to rename the files, but having the command create a non-working scaffold (at least on some environments) is very frustrating for beginners, so minimally the template files should be renamed as suggested above.
