If you take a look at the doc page, you can see that the content is properly formatted. Those blocks are parsed by MkDocs which extends Markdown syntax.

Code Review

This pull request updates the markdown formatting in multimodal_inputs.md to improve syntax highlighting in code blocks. The changes involve replacing mkdocs-material specific admonition syntax (!!! note, ??? code, etc.) with standard markdown blockquotes and fenced code blocks. While most of the changes are correct and achieve the intended goal, I've found a few instances where the conversion to blockquotes has introduced incorrect indentation. This can lead to improper rendering of lists and code blocks. I've provided specific suggestions to fix these formatting issues.
