[TDF infra] Announcing Gitiles VCS browser (gitweb replacement) and https:// anon git URIs

[Stephan Bergmann]

One minor thing that cgit.freedesktop.org provides is a "Diffstat" block 
(listing all files changed) between the commit message and the 
individual files' diffs, see e.g. 
<https://cgit.freedesktop.org/libreoffice/core/commit/?id=ddcd36d9d6191bfba7dea179067767a9ee192608>.

That's not present at the corresponding 
<https://gerrit.libreoffice.org/plugins/gitiles/core/+/ddcd36d9d6191bfba7dea179067767a9ee192608%5E!/>. 
  Is there a way to add that, or a different form of URL that would show it?
