Support for operationName request field

[trmcnvn]

Describe the feature

Would like to be able to pass operationName to our server. While this field isn't required in a standard setup, it's great for logging & tracing requests on the backend.

Doesn't seem to be a way currently to get the name of the operation within the fetch handler as only the raw text and hash are passed down.

Quick look seems it would be as simple as passing the artifact name down to the fetch handler here:

houdini/packages/houdini/src/runtime/lib/network.ts

Lines 297 to 301 in 30a754a

	const result = await client.sendRequest<_Data>(context, {
	text: artifact.raw,
	hash: artifact.hash,
	variables,
	})

Won't be able to open a PR until the weekend, so opening this issue until then in case someone wants to take it.

Criticality

nice to have

hey @trmcnvn! Thanks for opening this. This is a perfect use case for #365 so I think your best off waiting a bit for that to be ready. It's my top priority right now and I'm trying to have something you can play with by the end of the weekend. At least now there's some social pressure to make sure I hit my internal deadline 😅
