crates: Use `?include=` to reduce crates.io backend load (#9081)

By default the `/crates/:crate_name` API endpoint returns the categories and keywords related to the crates. Unfortunately this causes two additional database queries on the crates.io backend.

This commit change the request URL to use `?include=` to only include the additional metadata that is needed for the requested badges.
