VS Code extension attempts to launch Windows language server when remoted to Linux

[cgranade]

Describe the bug

When using remote development from VS Code (win10-x64) to use a VS Online environment hosted on Linux, the Q# extension for VS Code still attempts to launch the Windows version of the language server. Notably the Linux version is still correctly downloaded.

To Reproduce

Create a VS Online environment and connect to it from VS Code running on Windows. Install the QDK extension into the environment.
