feat: support using delimiter in scope-enum

[colinaaa]

Description

Currently, if the scope in message has delimiters(/, , or \), it is considered as multiple scopes and is tested separately.

I add extra checks to see if the scope matches the enum directly to allow 'scope-enum' to have delimiter.

Motivation and Context

Scope should be able to have delimiter like /. And tests should pass when 'scope-enum' is configured to have delimiter.

Usage examples

// commitlint.config.js
module.exports = {
  rules: {
    'scope-enum': [
      RuleConfigSeverity.Error,
      'always',
      [
        'foo/bar',
      ],
    ],
  },
};

echo "fix(foo/bar): qux" | commitlint # fails

⧗   input: fix(foo/bar): qux
✖   scope must be one of [foo/bar] [scope-enum]

How Has This Been Tested?

1. A multipleSlash test case is added.
2. Check if adding foo/bar to scope-enum would work.
