Enable Github Actions for Checkstyle

Enhancement Request

Is your enhancement request related to a problem? Please describe

I noticed that there are folks working on issue #428 (#431), translating or removing Chinese chars in code.
Manually checking for this kind of code style can be a pain.
But, we can make the process of code style check automated with less pain by introducing Checkstyle into CI.

Describe the solution you'd like

I'd like to define a Checkstyle workflow in CI.
The Checkstyle workflow will fail if a bad code style is found and will provide a report after each run.
The report includes the code style issues found in the workflow, and it can be a reference for reviewers.

Describe alternatives you've considered

• Github Actions: Checkstyle check + reviewdog report
• Github Actions: Spotless check

Yes, we can also check our code style in IDE.
