Lintcheck: Support underscores replacement in URL crate names

The generated URLs use `{krate}` for the crate name. This works well for the first part of the docs.rs domain, but the second part is actually the root module, which requires a replacement of all dashes with underscores. This PR adds `{krate_}` for the root module name.
