Confusing error with quarto render when swapping input and args

Bug description

The following mistake was entirely my fault but I found the behavior slightly unexpected compared to standard command line interfaces and the error message made it difficult to immediately identify what the issue was. Running the following render command produces the below error.

$ quarto render --to html unvotes.ipynb
ERROR: The specified directory ('.') is not a Quarto project

I'm fine with the ordering of input vs args but it seems like swapping the order is an easy mistake to make and more helpful error message would be appreciated (e.g. invalid file path, --to does not exist, or something similar).

Start by reproducing the quarto render --to html unvotes.ipynb command and inspect the quarto render CLI argument handling. The issue is addressed when this swapped-order mistake produces a clear diagnostic identifying the invalid input or argument instead of reporting that . is not a Quarto project.
