Proposal: replace toml formatter with taplo

[waynexia]

Is your feature request related to a problem or challenge?

We now using tomlfmt to format our Cargo.toml manifests https://crates.io/crates/cargo-tomlfmt. It

• is not actively maintained
• is not configurable
• is not convenient to use under our multiple sub-crate structure
• lacks of IDE supports

Describe the solution you'd like

I'd like to propose taplo tool, which looks more powerful. E.g., It has a vscode extension even-better-toml and can detect multiple toml files automatically. Also it has some format configurations I like, e.g. break line for long array.

Describe alternatives you've considered

Keep using tomlfmt.
