fix: convert 4-space indented callback params to Markdown lists in validate.md

Callback parameter descriptions were indented with 4+ spaces for visual
hierarchy, but Markdown interprets this as code blocks. Converted all
such sections to use nested unordered lists, which render correctly
while preserving the visual structure.
