Avoid duplicate JS error messages on UI (#28873) (#28881)

Backport #28873 by wxiaoguang

Gitea treat JS errors seriously, so sometimes the JS errors caused by
3rdparty code (eg: browser extensions) would also be reported on Gitea
UI: TypeError: WeakMap key undefined (caused by extension DarkReader's
bug) #28861

To avoid fill the user's screen with a lot of error messages, this PR
merges the same error messages into one.
