Describe the problem

Hello Kimai-team,

we have bought the "Working Contract" plugin and want to update the plugin when there is a new version available, mainly to not miss possible security patches of the plugin.
I wasn't able to find a way to easily get informed when a new version for the plugin is available.

Describe the solution you'd like

I have two ideas for this:

1. There could be an RSS feed for each plugin that could be used to post about a new release for the plugin. This would make it easy to get notified upon the release of a new version.
2. In the Kimai instances under System > Plugins the versions for the plugins are already listed, but maybe there is a way to show that a new version for an installed plugin is available. Although this would not help me as much as the first approach, it would help showing that the currently installed version is out of date.

Describe alternatives you've considered

I have considered either writing my own script to check for changes in the html of the plugin page or using a service like ChangeTower.
