Quarto oddities

[roaldarbol]

There are a few things that are causing hickups for Quarto.

1. Reserved parameter names. I currently cannot make a parameter named funding under the custom format options. It seems to be reserved somehow, and only returns true, while changing the name to part-funding allows it to parse the text.
2. Adding backslashes in strings that are provided in YAML. So either I figure out how to get around it or otherwise I'll unfortunately have to regex remove the backslashes.

There are also some fields that are missing (not present at least) in Quarto, such as github and short-title.

I have some issues with providing nested metadata via the CLI for testing, see: quarto-dev/quarto-cli#12313
