fix: MarkdownRemover updates

[chr15k]

Description

• Condense duplicated regex
• Regex to remove more than 2 layers of emphasis

Motivation and context

This contribution is for an open-source project I actively use. It aims to enhance the markdown remover functionality by adding support for removing triple emphasis from text and addressing some TODOs noted in the code comments.

How has this been tested?

The Docker README instructions didn’t work out of the box for me because Composer required a minimum of PHP 8.2 but 8.1 was being installed. I updated the default PHP version in the Makefile/docker-compose/Dockerfile to use PHP 8.2. Additionally, I encountered warnings related to the Docker configuration. However, I haven’t committed these changes to a separate PR since I’m unsure whether they are actual fixes or specific to my environment.

Tested using:

make tests-dox
