history link on mcr.microsoft.com is broken

The `history` link on https://mcr.microsoft.com/en-us/product/devcontainers/dotnet/about is broken.

I'm guessing this was specified as a relative link. It is intended to be a GitHub link (e.g. https://github.com/devcontainers/images/blob/main/src/dotnet/history) but when rendered in MCR it gets resolved to https://mcr.microsoft.com/en-us/product/devcontainers/dotnet/history.
