Add commit SHA to the datasheet(s)

[umarcor]

Since the datasheet is uploaded automatically from CI, multiple artifacts/assets might be difficult to tell apart. It would be desirable to have the commit SHA added to the frontpage/subtitle of the PDF and HTML datasheets, so that users can know which specific version of the repo they correspond to. It can also be useful for developers to understand bug reports or feature requests from users with probably outdated versions of the documentation.

However, I did not search how to do it with asciidoc(tor) yet. I'm creating this issue as a remainder.

If asciidoc supports this, this idea would be a nice add-on!
