### Bug description

The stdout of the embedded pandoc is getting redirected to stderr. For example:
```
quarto pandoc --version 2> /dev/null
```
outputs nothing (`2>` redirects stderr) but
```
pandoc --version 2> /dev/null
```
does output the version message.

This holds for other outputs of pandoc to stdout.

I am not directly affected by this, but I can imagine some piping scenarios where this could be pretty annoying.

VERSION:
```
$ quarto --version
1.1.251
$ cat /etc/os-release 
NAME="Fedora Linux"
VERSION="36 (Container Image)"
ID=fedora
VERSION_ID=36
VERSION_CODENAME=""
PLATFORM_ID="platform:f36"
PRETTY_NAME="Fedora Linux 36 (Container Image)"
```
