Crash on navigation to a dependency symbol when using OmniSharp

[AnInternetTroll]

Description:

Zed crashes when trying to navigate to a dependency's symbol or just
hovering over the symbol while holding down the control key.

Reproduction:

1. Install omnisharp-roslyn
   • (tested with version 1.39.11 and dotnet 8.0.3)
2. Clone Celeste64
   • I assume it can be reproduced with other dotnet projects, but
     haven't verified myself
3. Open Zed . in the repo, open Program.cs and hover over a dependency
   symbol while holding the control key. The program should crash
   quickly with the following error
