Fix: incorrect API response mark

[zuoningz]

Description of your changes

Some API have returns200 in the response, which would overwrite the desired API response format with a SimpleResponse object, which is a bug on the server side. This MR removes the returns200 field so that each API response will respond data in the wanted format

Fixes #

I have:

• Read and followed KubeVela's contribution process.
• Related Docs updated properly. In a new feature or configuration option, an update to the documentation is necessary.
• Run yarn lint to ensure the frontend changes are ready for review.
• Run make reviewableto ensure the server changes are ready for review.
• Added backport release-x.y labels to auto-backport this PR if necessary.
