Issue: Alone bold line formatting is escaped with markdown document 
<!-- Please note, this template is for bugs report, not feature requests -->

<!-- https://github.com/terraform-docs/terraform-docs/tree/master/CONTRIBUTING.md -->

**Describe the bug**
Using the output markdown document, I have an issue with alone bold line formatting. The `*` character is always escaped during generation.
 
**To Reproduce**

Steps to reproduce the behavior:

1. Create a module with a main.tf
2. Put those lines in main.tf:
```
/**
* **Please, read this line before starting**
*/
```
3. Run `terraform-docs markdown . > README.md` in module folder 
4. Content of README.md:
```markdown
\*\*Please, read this line before starting\*\*
```

**Expected behavior**

```markdown
**Please, read this line before starting**
```

**Version information:**

- terraform-docs version: 0.10.1
- OS: Ubuntu

Originally '*' was included in illegal characters to be escaped,
specifically when formatter is markdown or asciidoc. But there's no
real point of escaping asterisk, as markdown engines will process them
properly.
