Add the update bot

[noah1510]

This is about adding an update bot similar to the one arduino has.
It runs periodically and checks all registered repositories for new versions.
The difficult part is finding out if a found version already has an open pr.

• create a format for the data of the watched repos (url, provides, ci option, ...)
• create a workflow that runs periodically to check the watched repos
  • find an efficient way to check the tags without taking too much time (no clone unless new version)
  • check the wrapdb if the latest version is already in there
  • check the fork of wrapdb if it already has an update branch
  • use the update action to create an update
