docs: Add a note about gatsby-image fragments not working in Graphi…

…QL (#25387)

* Add a note about queries not working in GraphiQL

This is a known issue, but it could confuse new Gatsby users (like myself).

[See the `gatsby-image` docs for details](https://www.gatsbyjs.org/packages/gatsby-image/#fragments), and [this GraphiQL issue for progress on a fix](graphql/graphiql#612).

* chore: format

* Update docs/tutorial/gatsby-image-tutorial/index.md
