(converted to draft... there are other flags we pass in VS Code like --try-ports we also need to support)

Actually, I'm ditching --try-ports from VS Code since we're passing 10 which is the default value, but we did need allow-embedding.

(this is ready for review now and hopefully the bots will be green 🤞)

I'm surprised that these weren't passed through automatically since we pass any unhandled arguments along to the dds command

I was too.. seems to be a difference between arguments and the named options. There's an AllowAnythingParser that would allow these, but I think we'd then have to also read the other options ourselves, so since we only need these two I figured this was better. We can always revisit if we want to pass more in future.
