### Bug description

Attempting to publish to Netlify from RStudio Cloud via the RStudio Workbench terminal currently does not work:

```bash
/cloud/project/myblog$ quarto publish netlify

```

I believe the issue is that quarto is not detecting the RStudio Workbench (Prairie Trillium) environment correctly when quarto is invoked from the terminal. See https://github.com/quarto-dev/quarto-cli/blob/90c7f3ba42ffdae3c2b13ad3d1814f8aaaa14b9f/src/core/platform.ts#L32:L35

The issue may be that the expected ENV vars are not present in the terminal session, so quarto is attempting to open a native browser window which fails due to lacking a display. 
```
/cloud/project/myblog$ env | grep RS_
RS_RPOSTBACK_PATH=/usr/lib/rstudio-server/bin/rpostback
RS_SESSION_TMP_DIR=/var/run/rstudio-server/rstudio-rsession
RS_SERVER_RPC_SOCKET_PATH=/var/run/rstudio-server/rstudio-rserver/session-server-rpc.socket
RS_SERVER_LOCAL_SOCKET_PATH=/var/run/rstudio-server/rstudio-rserver/rserver.socket
RS_MONITOR_SOCKET_PATH=/var/run/rstudio-server/rstudio-rserver/rserver-monitor.socket
RS_SERVER_TMP_DIR=/var/run/rstudio-server/rstudio-rserver
```
