Why not support other props like body or query in NitroFetchOptions

[jcc1997]

I found $fetch missing type check for body which can be defined in eventhandler<{ body: MyRequestBody }>

[jcc1997]

nitro/src/types/fetch/fetch.ts

Lines 53 to 58 in b285a9d

	export interface NitroFetchOptions<
	R extends NitroFetchRequest,
	M extends AvailableRouterMethod<R> = AvailableRouterMethod<R>,
	> extends FetchOptions {
	method?: Uppercase<M> | M;
	}

I think add type infer in here should work. But why not before?
