Issue with multiple heading with same content

[mayankj007]

I have a document with have following structure

# Testcases

## Test Case 1
### Initial State
### Actions Taken
### Expected Result
### Actual Result

## Test Case 2
### Initial State
### Actions Taken
### Expected Result
### Actual Result

## Test Case 3
### Initial State
### Actions Taken
### Expected Result
### Actual Result

I am getting the following error in the lint:

MD024/no-duplicate-heading: Multiple headings with the same contentmarkdownlint(MD024)

My IDE details:
Eclipse Theia IDE
Version 1.50.100
VS Code API Version: 1.89.1

My understanding is, the lint should not through an error if the parent heading is different. As it can be a real world case.

By default, duplicate headings at any level are reported. If you want to allow duplicates across sibling sections as you show above, you need to set the siblings_only parameter in configuration. This is explained in the documentation: https://github.com/DavidAnson/markdownlint/blob/main/doc/md024.md
