Why
It might be valuable in some cases for docs users to know when the page they are viewing has been updated.
How
Add last modification date to page Footer based on the data from git about latest commit. The information is appended to the Markdown files before executing a deploy build at the cost of 30s-60s of CI run time. Locally, the data is not present, and we show a placeholder - this is the unsual pattern for docs frameworks including this functionality, i.e Docusaurus or GitBook.
Test Plan
The changes have been reviewed locally in development and static modes.
