Switch to VSCode extension "Even Better Toml"

[redeboer]

The VS Code extension Better TOML is deprecated and recommends using Even Better TOML instead. This should be fixed through the check-dev-files hook.

Main advantage: it has better language navigation, like navigating sections, which is a requirement for #98.
