Stable release fetch script updates workshop items that require 'latest alpha patch' even if new stable version is only a bug fix

```
[>] Searching releases with same major.minor...
[>] Searching workshop items with already existing major.minor...
[>] Updating workshop items with same major.minor to use latest patch as minimum game version...
```

This needs to be changed and should only work for `major.minor`, and not for `major.minor.patch`
