Display version numbers

[kbatuigas]

We'd like to have the "version number" be visible within the docs itself, and it would be nice if it could persist across the pages so that readers are able to easily tell which version they're reading, no matter where they are in the docs. Currently they can do so by referring to the URL, but something more explicit on the page itself would be a better experience.

If it's something that could be solved by front matter in Hugo we would be interested in learning how to set that up. Thank you!

Where is "version number" defined ?
Ex based on Front matter variable in .md file

----
my_version: 10.2.52
----

Version is {{< param my_version >}}
