`quarto_use_template` doesn't run if I'm not in an empty directory

Hi !

Some info on the code:

• I have a template in inst/templates/memo
• quarto_add_extension works well
• I'm using the dev version
• I don't have a template.qmd file at the root of mypackage

This isn't a reprex, let me know if that's needed

> create_memo <- function() {
+     template_path <- system.file("templates/memo", package = "wvc")
+     quarto::quarto_use_template(template_path, no_prompt = TRUE)
+ }
+ create_memo()
ERROR: Unable to install in /Users/josephbarbier/Desktop/wvc as the directory isn't empty.

I'm sure I'm doing something wrong, but I don't know how I'm supposed to use the quarto_use_template function? A few points:

• how do I run the function in a completely empty directory? Like, I need at least .R file anyway to run the code?
• Is there any way around this and say ‘create it here instead’?

I really feel like I've missed something because my questions are a bit stupid

Start by inspecting the quarto_use_template entry point and reproduce the reported call with a non-empty directory. Compare its behavior with quarto_add_extension and the Quarto CLI error shown in the issue. Done means the supported usage or destination behavior is clarified and covered by an appropriate regression test.
