Table of Contents on https://bazelbuild.github.io/rules_rust/flatten.html doesn't work

[jfirebaugh]

The links in the Table of Contents (first section) of https://bazelbuild.github.io/rules_rust/flatten.html (linked from https://bazelbuild.github.io/rules_rust/) do not work.

To take the first link as an example, there's no anchor corresponding to https://bazelbuild.github.io/rules_rust/flatten.html#CrateInfo.

Some of the links are working. Ones that are not: CrateInfo, DepInfo, StdLibInfo, rules_rust_dependencies, and rust_register_toolchains. Possibly others, I didn't test them all.

This was fixed by https://github.com/bazelbuild/rules_rust/pull/1444.
