`buck2 lsp` fails to start if there are type errors

[9999years]

If there are type errors present in the Starlark code (for the prelude, at least), the buck2 lsp will exit immediately with exit code 3 rather than starting with limited information available.

If type errors are introduced while buck2 lsp is already running, then buck2 lsp continues to provide information on a best-effort basis, rather than crashing or returning no data for all requests, so I believe starting up in the presence of errors should be possible.
