Change form actions to fetch for submit review box (#25219)

Co-author: @wxiaoguang 

Close #25096 

The way to fix it in this PR is to change form submit to fetch using
formData, and add flags to avoid post repeatedly.
Should be able to apply to more forms that have the same issue after
this PR.

In the demo below, 'approve' is clicked several times, and then
'comment' is clicked several time after 'request changes' clicked.

After:
