fix: use different rust toolchain for foundry builds

[Maddiaa0]

Overview

Cargo version installed by default in build-images was not the minimum required for the newer release of foundry that was pinned in #8868, this alters the foundry-build earthly script to use 1.80 rustc version. This is set through adding a toolchain file so the correct binary will be installed automatically.

In the future if we need to bump the version for builds, we can just alter this toolchain version.

This also runs forge fmt for this updated version

Interesting, have not seen this before

doing it 1000 times in a loop in this test, for each tree. Was making it exceed limits. I assumed its fine to just not meter as we dont use it like this in prod.
