Could one pass the "lang" parameter via quarto_render?

Related to quarto-dev/quarto-cli#275

I'd like to use a single Quarto configuration file for books in two different languages.
I can edit it via an orchestration script but I wonder whether one could override what's in the configuration file via an argument of quarto_render()?

Maybe as Pandoc with --metadata-file=FILE (https://pandoc.org/MANUAL.html) 🤔.

Hopefully this will work as expected. Keep me updated. I know we have some side effect in quarto itself

• metadata override through CLI flags is inconsitent quarto-cli#6123

@maelle what about using a project profile?
