S3E5 meeting minutes have problem to show the PDF files.

Separated from #358

@fuyunfuyun666 @CyFeng16 The reason of the PDFs in S3E5 can not be displayed is not related to this deploy issue.

It's because the URL of the PDF is not right. @gaojiuy had made the same mistakes as the @ArronHZG before: use the Github file url(wrong) instead of it's AMC URL(right).

It should be fixed as I demonstrated from the blowing DIFF.

Is there anyone who wants to help @gaojiuy to send a PR to fix it?

Great.

I'd like to suggest that we should reference the ISSUE in our PR so that we can connect everything together. (which I had just modified the PR of @gaojiuy
