Add version info of app to uptime kuma

[CommanderStorm]

I don't know which of these you are requesting about:

• Version information ABOUT uptime kuma
  Please refer to #4730 for an in-depth discussion how we currently handle this, how we report being outdaed and how to recieve notifications for this
• Version information ABOUT thrid party systems
  How would we know this? Third party systems don't follow a set standard on this one
  => I think this part is kind of impossible unless I am missing something.

@CommanderStorm hi, im talking about 3rd party systems.

Im fully aware, that every system has "own" type of response. but Many users of uptime kuma are developers of that 3rd systems. So, if you create optional option ( you can chose whatever format you want - for example field, when you put path to this version field or just you will hardly define where it should be) to enable and config this version info, we can adjust our system to provide such info. It will be really helpfull. Thank you.

Parsing the field automatically is tracked in #892
Adding public descriptions is tracked in #938 (there is also a hacky workaround noted here)

=> Think this resolves your question.
