Output Markdown is missing some newlines, but not all

When running documentation on a project or single file, from powershell CLI or built in VSCode CLI, markdown and html formatting is messy.

**Version:** `14.0.1` & `14.0.0`

**Input code:**
```typescript
/**
* Extracts a literal value by removing double curly braces
*
* @since v0.0.1
* @category Helpers
* @param {string} val - The string to process
* @returns {string}
* @example
* getTemplateLiteral('test') //=> ''
* getTemplateLiteral('{{test}}') //=> 'test'
* getTemplateLiteral('{{{test}}}') //=> '{test}'
* getTemplateLiteral('{{}}test') //=> ''
* getTemplateLiteral('{{}}') //=> ''
*/

export const getTemplateLiteral = (val) => {
if (String(val).startsWith('{{') && String(val).endsWith('}}')){
return String(val).slice(2,-2);
}
return '';
};
```

Command from CLI: `documentation build src/helpers/getTemplateLiteral.ts -f md -o README.md`

**Output README.md:**
````markdown

````

Not sure if I've made a mistake here, but the output seems to be formatted very strangely, is this a bug?
