[Bug]: Images from markdown file are not removed

[TomskDiver]

Bug Description

Images from markdown file are not removed because error in regex pattern pattern = r"!{1}\[\[(.*)\]\]": https://github.com/run-llama/llama_index/blob/main/llama-index-integrations/readers/llama-index-readers-file/llama_index/readers/file/markdown/base.py#L79

But markdown syntax for images it ![alt_text](path_to_image_file) (see https://www.markdownguide.org/basic-syntax/#images)

May be correct regex is !\[.*\]\(.*\)

FYI @hursh-desai, @jerry

@TomskDiver Hello there! 👋 I'm here to help you with bug fixes, questions, and contributions.

The regex pattern in the remove_images function of the MarkdownReader class should indeed be corrected to properly remove images from Markdown files. The current pattern r"!{1}\[\[(.*)\]\]" is incorrect. The correct pattern to match the standard Markdown image syntax ![alt_text](path_to_image_file) is:

pattern = r"!\[.*?\]\(.*?\)"

This pattern will accurately capture and remove images from the Markdown content, ensuring that the output is as expected ^[1].
