[Feature Request] Allow GET comments reactions without token via API

[meteorlxy]

Description

Related to #9220

Currently, we can:

• GET issues: https://gitea.com/api/v1/repos/meteorlxy/vssue-test/issues?q=[Vssue]Vssue+Dev
• GET comments: https://gitea.com/api/v1/repos/meteorlxy/vssue-test/issues/1/comments

But we can't GET reactions if we don't pass token (get 401):

• GET reactions: https://gitea.com/api/v1/repos/meteorlxy/vssue-test/issues/comments/104283/reactions

Hope the behavior of reactions API can be consistent with the former two APIs.
