Remove debug statements from CI workflow

Remove accidentally committed debugging commands from the 'Print Rust
toolchain default versions' step that were used to troubleshoot a build
issue. These commands (ldd --version, ls contract-bindings/src, cat
contract-bindings/src/lib.rs) are unrelated to printing Rust toolchain
versions and unnecessarily pollute CI logs.
