Repo File Sync: .sync/rust_config/rustfmt.toml: Use Rust default of 4…

… space indentation (#1058)

## Description

Format only. `rustfmt.toml` now defaults to tab_spaces to 4 (earlier 2).
No functional changes. No files were actually changed by cargo fmt --all
command in this repo (as there is no cargo.toml in the repo).
