.qmd files as document templates

There's a feature request to support customizable Quarto templates in the "New Quarto document" workflow for RStudio: https://github.com/rstudio/rstudio/issues/11316 -- this is likely a better fit for Positron and after discussion with Sharon, perhaps part of the new Welcome Page/New Project flow.

I'm not 100% sure this is a new feature request, or even whether this is the right repo to open such an issue, but it could be cool and useful to be able to select templates for .qmd documents in the same way you can for .Rmd documents. In the below screenshot I guess my feature request is for a new option underneath 'Interactive' called "Template" or similar. This would enable/encourage others to develop their own .qmd style documents as enabled/encouraged by the rticles package (where I thought about opening this issue).

A way of creating .qmds based on templates from the command line, e.g. with rstudioapi, would also be on my wish list although that may be best handled by things external to RStudio. Apologies if you're already on the case with this and hope this request is of use/interest in any case!

Start by reviewing the existing “New Quarto document” workflow and the proposed Welcome Page/New Project flow, then compare the related RStudio issue #11316. Check how .Rmd templates are handled and whether rstudioapi or another external component owns command-line creation; done means the appropriate flow can select and create customizable .qmd templates.
