docs: Convert a semantic version to a minor range.
  
  In composer.json entries for Drupal core or other major projects, we often
  want to designate the version similar to '^8.2'. This code converts version
  strings that may have a pre-release suffix to such a range.
  
  Furthermore, there are some edge cases wherein we may want to take a version
  that is already a minor range, such as 8.x, and use it as is.
