Description

I started upgrading to Gatsby 4 and am getting a warning when running gatsby develop:

warn Warning: there are unknown plugin options for "gatsby-remark-images": withAvif
Please open an issue at ghub.io/gatsby-remark-images if you believe this option is valid.

I have version 6.0.0 of gatsby-remark-images installed and simply set withAvif: true. The docs still list the option withAvif, and avif images are also being created.

Minor, but shouldn't show up afaict.
