Language Server Should Garbage Collect in Workstation Mode

## Issue description
The language server installs with the default garbage collection in time efficient server mode, as opposed to aggressively memory efficient workstation mode. This causes the language server to consume all available memory. Differential diagnosis is revealed by setting the environment variable `DOTNET_gcServer=0`, which resolves all memory consumption after reloading the user environment.

## Steps to reproduce
0. Ensure the DotNet 7 runtime is installed in a Linux based OS.
1. Install the CSharp extensions.
2. Open a CSharp project.
3. Enjoy watching all your available memory disappear until your system freezes.

## Expected behavior
As the language server exclusively runs on development workstations its garbage collector can safely default to running in the more aggressively memory efficient workstation mode, to conserve memory resources for other workstation processes.

## Actual behavior
The language server runs in server garbage collection mode, eventually using up all available memory.
