Polish Chinese translations related to “comments”.

[huajiankan]

Re-checked the wording based on the feedbacks of #1100, generally separating two kinds of comments which appear in the editor/code and code review discussions.

This PR refers to the latter case, updating the comments appearing in the discussions within the scenario of code review / pull requests. Take a typical example, the current translation of commentReply-newComment is 键入新注释, which is obviously inappropriate; have changed to 添加评论 in line 4593. Same with others.

BTW, changed the wording within commentsEditorContribution from 评论 to 注释 (Line 4616-4617), following the principle of 'comments apprearing in the code mean 注释'.

This might be a good PR to solve and fix #1100
