Minor fixes for README

[KengoTODA]

Describe what this PR does / why we need it

I just found minor issues in README files, so want to suggest these fixes.

Does this pull request fix one issue?

NONE

Describe how you did it

• Replace "，" with ","
• Replace "。" with "."
• Correct wrong copyright holder info

Describe how to verify it

Probably we need to ask a human to review manually :)

Special notes for reviews

Sorry for such minor and small proposal!

@zhongxig can I ask why we reverted this change?

I believe that we need to tell the copyright holder of this project. Refer to the following projects as live examples:

• https://github.com/actions/setup-java/blob/a12e082d834968c1847f782019214fadd20719f6/LICENSE#L4
• https://github.com/google/dagger/tree/b9ed2f0d4d16ceee12fdbf2821e101ddc917ff75#license
• https://github.com/facebook/react/blob/529dc3ce84f0efe99a8be33ff453c09d5801d5ca/LICENSE#L3

The copyright of license is usually described in the license distribution page. In this case at the footer in the license distribution page. So we do not need to write its copyright holder here, which may lead readers to misunderstanding.
