Add sensor that detects MySkoda API problems

[WebSpider]

Is your feature request related to a problem? Please describe.
Problems with the MySkoda API leave this integration semi-functional only. When this happens, I don't know what's causing the issues.

Describe the solution you'd like
Know when there are issues with the MySkoda API so I understand what's going on

Describe alternatives you've considered
So far I have used Discord to see if "it's just me, or the world as well".

Additional context
There are some API's that detect if a service is having issues. We may use those.
