add format checker to .toml

[georgehao]

This pr is to resolve the #13821 (comment)

The issue detail:

1. most of the reth Cargo.toml indentation use space, but some files use tab

Tab: https://github.com/paradigmxyz/reth/blob/main/crates/ethereum/evm/Cargo.toml#L49
Space: https://github.com/paradigmxyz/reth/blob/main/crates/trie/trie/Cargo.toml#L74

if I open the auto format option in Rustrover, some unexpected formats appear.

suggest use the rule: "Use spaces instead of tabs"

2. some Cargo.toml files have redundant space

reth/Cargo.toml

Line 467 in 1296bac

op-alloy-rpc-types-engine = { version = "0.9.6", default-features = false }

• check failed: https://github.com/scroll-tech/reth/actions/runs/12948005311/job/36115756610
• check success: https://github.com/scroll-tech/reth/actions/runs/12948028437/job/36115822655?pr=145

Updates

So add a .toml checker here and add lint-cargo-toml to Makefile

I already know that this will cause issues because people use different formatters for toml

before we can consider this, this definitely needs a makefile command to format all cargo.tomls and a note in the formatting section, otherwise this will cost me a lot of time when I need to touchup prs.
