get latest patch versions from repo

This commit introduces the following changes in the logic of the script:

- The scripts performs one call to fetch the latest minor version from the main repo
- For each of the potential labels, the scripts
    - Estimates the version label for potential labels that use the latest version (by mistake)
    - Makes one call for each potential label to fetch the latest from the repo
    - For cases where parsing of the minor version of a potential label is wrong, the calculated version is used as fallback
