PR Summary

• Modified Documentation
  The content of the README.md file, which is the introductory document that explains what our project is about, has been updated.
• Adjustment of Text in the Document
  A passage in our document has been smoothed out to improve readability. The revised text now indicates that "From Breezejp v1.64, we have supported Japanese pagination."
• Changed URL Address
  The URL redirecting to the Japanese language version has been updated to point users to the English language version instead - a vital update for non-Japanese speakers to understand our project better.
• Updated Visual Content
  Images, which aid in understanding the project, have been added or updated, making the overall documentation more informative and visually appealing.
