quarto create capitalizes the qmd file name

[nealrichardson]

Bug description

When I do quarto create my_project_name, I get my_project_name/My_project_name.qmd created. It's odd that the qmd file name is capitalized.

Steps to reproduce

quarto create project default my_project_name 

Expected behavior

% quarto create project default my_project_name 
Creating project at /Users/me/my_project_name:
  - Created _quarto.yml
  - Created my_project_name.qmd

Actual behavior

% quarto create project default my_project_name 
Creating project at /Users/me/my_project_name:
  - Created _quarto.yml
  - Created My_project_name.qmd

Your environment

MacOS 13.6.3
zsh
