Setup copied from PageProps (tho not sure if I should also add Location part, we should decide on that, because generics are position arguments, so trying to add it later would be a problem):

gatsby/packages/gatsby/index.d.ts

Lines 87 to 154 in fe65c29

	export type PageProps<
	DataType = object,
	PageContextType = object,
	LocationState = WindowLocation["state"],
	ServerDataType = object
	> = {
	/** The path for this current page */
	path: string
	/** The URI for the current page */
	uri: string
	/** An extended version of window.document which comes from @react/router */
	location: WindowLocation<LocationState>
	/** A way to handle programmatically controlling navigation */
	navigate: NavigateFn
	/** You can't get passed children as this is the root user-land component */
	children: undefined
	/** The URL parameters when the page has a `matchPath` */
	params: Record<string, string>
	/** Holds information about the build process for this component */

	matchPath?: string
	}
	}
	/**

With Head the location will only ever be pathname so there won't be a need for LocationState generic

So we can skip that

this is entire fix, rest is just added tests and updated HeadProps type
