Add support for outputing version also on Windows runner

[cderv]

Follow up on #52 and cecee4b

Possibly using quarto --version is the simplest way to support all OS

This is slightly different (broader) than this issue, but I just revisited #52 when trying to decide how bleeding edge to go with local Quarto. I don't want too big of a difference between my local installation and the version being used to actually render the R Packages book. #52 got closed, but I still don't see a "nice", official statement of the installed Quarto version in my logs. Example: https://github.com/hadley/r-pkgs/actions/runs/3844629563/jobs/6547904956. Although I can of course figure it out from lines like this:

Preparing to unpack .../quarto-1.2.280-linux-amd64.deb ...
Unpacking quarto (1.2.280) ...
Setting up quarto (1.2.280) ...

I think what I'm expecting or hoping for is some equivalent of how the session info is reported:

https://github.com/hadley/r-pkgs/actions/runs/3844629563/jobs/6547904956#step:7:5355

which reminds me that perhaps the or "a" solution to the problem is to have the Quarto version reported there, which is r-lib/sessioninfo#75, which I've apparently linked to before 😅
