VS Code extension does not activate if project contains `.bsp` folder

[ahoppen]

If your project contains a BSP server config in a .bsp folder as described in https://build-server-protocol.github.io/docs/overview/server-discovery, SourceKit-LSP can handle the project and the VS Code extensions should thus activate.

swiftlang/sourcekit-lsp#1728 implemented this lookup logic in SourceKit-LSP. I think we can ignore the global BSP search paths for now.

I think this will be resolved with #1792

Oh, great!
