fix: reorder markdown processing to run prettier after markdownlint

Changed the order of steps in generate-docs action:
- Old order: textlint → prettier → markdownlint --fix → validate
- New order: textlint → markdownlint --fix → prettier → validate

This ensures prettier's table formatting (with aligned columns) is
the final result before validation, avoiding MD060 lint errors.

Also added ignoreReturnCode: true to markdownlint fix step so it
doesn't fail on unfixable issues before prettier can format.
