Added latest version info to footer when logged in as admin

[ZoesDev]

Describe the solution you'd like This is a nice to have feature. where when you are logged in as admin it would be amazing to have a notification even if it is where the version is in the footer of hey there is a updated version to your instance available. This could be something as simple as this

Version: 0.99.1 (c4f9cf89) !update available

Or we could expand it with

Version: 0.99.1 (c4f9cf89) !Version 0.102.2 is available for download

This maybe best if it is run as a job that runs like once a day or maybe every hour or 2 hours so it isnt hitting githubs servers checking on every page refresh and updates a table in the database and pull from there.

Additional context here would be the endpoint todo that can do this, with 0 being the newest release/tag

https://api.github.com/repos/manyfold3d/manyfold/tags

There is also the https://docs.github.com/en/rest/releases/releases?apiVersion=2022-11-28 but it needs a Bearer token to use where as the tag endpoint doesnt.

this could also use ghcr.io for the container endpoint so it is on each type. but It appears to be needing a API key for this endpoint to work.

Here's a quick hack I did to check feasibility:

diff --git a/app/views/application/_footer.html.erb b/app/views/application/_footer.html.erb

 end

We can easily get the upstream tags and sort descending. Then we can store this and add it to the initializer.

We can't use the API without an auth token but we can get the tags anonymously through a git ls remote. As long as semver is strictly adhered to.

The next parts to this are the cronjob to update the version number as the application is running.

I think that will only work on a git checkout, which I don't think you can do inside the docker container. Good news though, there's an atom feed for releases! https://github.com/manyfold3d/manyfold/releases.atom

We could add a scheduled sidekiq job (like CacheCleanJob or UsageReportJob) which pulls the atom feed regularly and sets the latest release in a SiteSettings.latest_version field. Then that could be displayed however appropriate in the UI.
