Broken link in the "Connections" documentation page

In the documentation page [Guided Tour > List Data > Connections](https://relay.dev/docs/guided-tour/list-data/connections/) there's a problem in the internal link where it reads `If you're curious to learn more about the details of cursor-based pagination and connections, check out [the spec]`(https://relay.dev/graphql/connections.htm/).

This link takes you to a 404:
.

Open the Guided Tour > List Data > Connections documentation page and inspect the internal link labeled “the spec.” Visit the current target and confirm the 404, then verify the corrected destination resolves and the page renders the link properly. Done means the link no longer returns a 404.
