## Short roundup of the initial problem
It was mostly out of date because we have to manually update it with our current version number.
The use of that is suspect anyway, since it only displays in the appveyor build overview.
It also had a redundant info about the branch.
## What will change with this Pull Request?
- remove hard coded version number
- remove branch
- cleanup build trigger from [#3300](https://github.com/Cockatrice/Cockatrice/pull/3300/files#diff-11c909939117928998b102a1fff7d363)
- more readable style
