/**
* Detect semantic commits by counting the number of commit messages that match the Angular convention and comparing it to the number of commit messages that do not match the convention.
* The Angular convention is defined as: `<type>(<scope>): <description>`, where `<type>` is a word, `<scope>` is an optional word, and `<description>` is a string.
*
* @see Inspired by {@link https://github.com/conventional-changelog/conventional-commits-detector|conventional-commits-detector} and {@link https://www.conventionalcommits.org|conventional commits specification}.
* @param commitMessages commit messages to check
* @returns A number greater than zero if more semantic commits than non-semantic commits, less than zero if more non-semantic commits than semantic commits, or zero if equal number of semantic and non-semantic commits
