Unhandled exceptions on language server startup are not logged by E2E tests

I was investigating an issue with the language server E2E tests failing on the official build (worked on GH). Pulling the VSIX produced by the build immediately showed the failure, but the errors were missing in the log we're collecting.

The easiest way to repro, simply remove the snippet directory before launching the language server. You should see the errors similar to the ones below. We need to make sure that we collect these in the test logs to make debugging easier.

```

Reproduce the failure by removing the snippet directory before launching the language server, then inspect the E2E test log collection. Start with the startup path in src/Bicep.LangServer/Program.cs and the related Server.cs and ResourceSnippetsProvider.cs stack-trace entries. Done means unhandled startup exceptions appear in the E2E logs.
