Build (without lock) fails – mdbook has undone their breaking update to their public toml dependency

[steffahn]

Here’s the revert in mdbook’s repo. Here’s the relevant PR in this repo that made mdbook-toc follow the change (to fix build errors at the time).

And the unsurprising compilation error

    Checking mdbook-toc v0.14.0 (/…/mdbook-toc)
