Fixes fmt, aligns Makefile with CI/CD pipeline

Buildkite failed on rust fmt step, this fixes that error.
Also aligns rust fmt call in our Makefile with the one used in buildkit.

- Call to fmt in our Makefile was
  - cargo +$(RUSTFMT_TOOLCHAIN) fmt

- Call in buildkite is
  - cargo +nightly-2024-04-22 fmt --all -- --check

- Call to fmt in our Makefile is now
  - cargo +$(RUSTFMT_TOOLCHAIN) fmt --all -- --check
