gh actions to render site

[isabelizimm]

Quarto has github actions functionality-- it seems like we are pretty close to being able to delegate rendering + publishing to GHA on the vetiver site.

There are a few things that are currently not automated, that are blocking this:

• [ ] creating new plot for python monitoring (probably can become automated)
• [ ] awkward code chunk breaks when output: false
• [ ] anything else?

It makes some sense to me to render the site with actions currently, even though we have longer-term goals to bring the API docs onto the site (which will be a little more complex with actions). WDYT?

I think this is a great idea! 🙌 If you want to start setting it up, I can do a review or give feedback.
