fix: error when github does not respond with expected data.

[Buco7854]

In case of a ratelimit github does not answer with the expected tag_name resulting in an error and therefore making the UI unusable.

I propose to make it so that if the expected tag_name key is not present replace it by the current version so that it does not result in an error and does not trigger update notification.

Should fix #70

I think this should be seen more as an temporary mesure to implement a check that would not trigger rate limit that easily. Making a request to github API each time someone access a page in the web ui make it so that you get ratelimited pretty fast, and without even talking about the fact that it blocks the ui completly this may block other services using the api in the network. Maybe a button to check the version in the admin panel would be better. Or it could be completly removed. Since it's checking against github there is already a way to be alerted when a new released is out by github itself so I dont think this is really needed.

The function has also been changed to only send requests once per day to check for available updates
