Add additional anchor to match GitHub TOC rendering
GitHub uses lowercase for anchor links, and correspondingly any TOC
references are written to use the same. This results in TOC's that work
when viewed in GitHub, but are broken in Gitiles, and vice-versa.
Add a second anchor using lowercase for the name and id to ensure that it
matches the GitHub flavour of markdown, without breaking existing usage.
