Add Quarto Pub option to quarto_publish_doc() and quarto_publish_site()

[davidkane9]

The help page for quarto_publish_doc and friends specifies that:

Publish Quarto documents to Posit Connect, ShinyApps, and RPubs

It would be helpful if these functions also allowed us to publish to Quarto Pub. My specific use case is helping beginner students to put a Quarto website on the the web, for all to see for free. Posit Connect costs money while ShinyApps and RPubs do not handle websites. So, I think my only option is to show students how to use Quarto CLI, which is tough for beginners.

This will be done by wrapping the quarto publish command.

• quarto publish wrapper  #101

rsconnect package is also now the recommended way to publish to Posit Connect, Posit Cloud and ShinyApps.io

We'll soon deprecate those functions

• Deprecate quarto_publish_*() in favour of rsconnect functions #102

So options will be

• rsconnect for some providers
• quarto publish command (and the wrapper that will be available in this package soon) as other options (like Quarto Pub).

It is the same team working on both Quarto R package, and Quarto CLI and so work need to be split, and priority is just right now on the CLI. I'll do an update of Quarto R probably after next CLI update.

Just to be clear, I am closing because of the two linked issue existing already.

So, I think my only option is to show students how to use Quarto CLI, which is tough for beginners.

Posit Cloud is another option that is available through rsconnect package in the meantime if this helps to have an R wrapper. But it requires a Posit Cloud account I guess.
