ci: add reviewdog workflow for yamllint action

[waterfallmouse]

Overview

This PR involves formatting improvements to the ReEarth-CMS Integration API schema definition file, as well as the addition of GitHub Actions to enhance our code review process.

What I've done

• Formatted the YAML file to fix inconsistencies in indentation and unify formatting styles.
• Cleaned up the structure of responses and requests for each API endpoint to enhance readability.
• Added a new GitHub Actions workflow file .github/workflows/reviewdog.yml to integrate reviewdog with yamllint for automated linting on pull requests.

What I haven't done

• Since these changes do not affect the functionality of the APIs, I have not conducted endpoint functionality tests.
• This PR does not include any changes or additions to API functionalities.

How I tested

• I parsed the file in a local environment to ensure the YAML syntax was correct.
• Used a visual diff tool to confirm that there were no unintended differences between the versions before and after the changes.
• Tested the new GitHub Actions workflow by simulating a pull request to ensure it triggers correctly and performs the intended linting tasks.

Screenshot

• None.

Which point I want you to review particularly

• Please review if there are any further improvements that could be made to the formatting of the YAML file.
• Feedback on the setup and configuration of the GitHub Actions workflow would be appreciated to ensure it meets our CI/CD standards.

Memo

• The main purpose of these changes is to improve readability and maintainability.
• The addition of the GitHub Actions workflow is aimed at automating our review process, ensuring consistent code quality, and streamlining our development workflow.
• This cleanup of the foundational schema sets the stage for future changes and expansions to the API.
