Implement a Build Number

[parkview]

Is your feature request related to a problem? Please describe.
Currently there is no webpage that lists the current build that is running. While the CHANGELOG does list git tags of the repo, it's not visible via the make-hub webpage menu

Describe the solution you'd like
Investigate how to hook into a github action, to automate the generation of a build number. This number or token could then be be incorporated into the CHANGELOG file and into the help.pt template.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context
Ideally clicking on the maker-hub ? (help) menu icon (http://localhost:8080/help), will display the build number of what is running. There should be a link to the github maker-hub project page that displays the current build. This way people can see if they need to update the locally installed project

Ideally, (maybe should be lodged as another issue?), the local maker-hub should check the github maker-hub repo to see if a newer version have been released.

this should live under the info page http://x.x.x.x/info, along with any other relevant information that can be useful in helping to diagnose problems.

see issue #60 for intended help icon usage.
