ModuleHandler::parseDependency() can deal with beta1 but not beta

Problem/Motivation

As part of refactoring and improving Drupal's harmony with semver, it's been discovered that ModuleHandler::parseDependency() expects dev versions to end with a number.

For instance, views_ui(8.x-1.1-alpha12) can be parsed, but views_ui(8.x-1.1-beta) can not.

That's because the regex looks like this: $p_minor = '(?<minor>(?:\d+|x)(?:-[A-Za-z]+\d+)?)';

You can see this reflected in the test data: https://cgit.drupalcode.org/drupal/tree/core/tests/Drupal/Tests/Core/Ext...
