/**
* @module compareSemver
* @description Compares two software version numbers (e.g., "1.2.1" or "1.2b") and determines the type of version change.
* The first version to be compared, and the second are passed as argument 1 and 2 or as array of 2 items.
* When V1 > V2 the it means and upgrade.
* @param {string[]} versions - V1 and V2 in Semver format
* @returns {string} It returns a string of either:
* 'major' if the major version is incremented.
* 'minor' if the minor version is incremented.
* 'patch' if the patch version is incremented.
* 'downgrade' if the second version is lower than the first.
* 'equal' if both versions are equal.
* 'error' if the comparison is abnormal or cannot be determined.
* @example {{ ["1.2.3", "1.2.1"] | compareSemver == "patch" }}
* @license MIT
