ci(workflow): add pull request trigger sdk generation and cleanup artifacts step

[Junjiequan]

Description

This PR resolves SDK generation issues caused by incorrect @ApiProperty definitions in DTOs and enhances workflows to ensure SDK generation is validated during pull requests.

Workflow Changes:

• Added support for triggering workflows on pull_request events targeting the master branch.
• Ensures SDK generation is tested as part of the CI workflow for pull requests.

DTO Refactoring:

• Fixed @ApiProperty definitions in UpdateDatasetDto:
  • Changed type: [String] to type: String with isArray: true to resolve SDK generation issues.
  • Improved descriptions and default values to align with Swagger and SDK requirements.

Motivation

We want to ensure better testing coverage during development by validating SDK generation in pull requests. This helps catch issues early, such as the previously encountered problem with incorrect @ApiProperty definitions (type: [String]), which caused SDK generation failures.
