Original GitHub issue: https://github.com/DavidAnson/markdownlint/issues/394

When using a special value "*" for zero or more headings, subsequent required headings in the rule are ignored.

For example, if you change the following line to any value, the tests will continue to pass: https://github.com/DavidAnson/markdownlint/blob/main/test/required-headings-zero-or-more.json#L9 .

I.e.

{
  "default": true,
  "MD043": {
    "headings": [
      "# One",
      "*",
      "### ANY VALUE HERE1",
      "*",
      "### ANY VALUE HERE2",
      "*",
      "#### ANY VALUE HERE3"
    ]
  }
}

This markdown will still show no errors regardless of whether the "ANY VALUE HERE" header is present or not.

# One

## Two

### THREE

## four

## Five

### SiX

#### 7

This looks to be related to the change here: github.com/DavidAnson/markdownlint@e20502c494 .
