Custom Router release builds are failing on Rust 1.78

Describe the bug

Release builds of project created with

cargo-scaffold scaffold https://github.com/apollographql/router.git -r apollo-router-scaffold/templates/base -t main

when built with Rust 1.78 and ran by providing the demo supergraph schema (starstuff) is failing with these errors

To Reproduce

Set Rust version to the latest stable release using rustup default stable and then run

cargo-scaffold scaffold https://github.com/apollographql/router.git -r apollo-router-scaffold/templates/base -t main
cd starstuff
cargo build --release
target/release/router --supergraph supergraph-schema.graphql

Expected behavior

It should run as expected. This works fine though when built with Rust 1.76
