feedback from review

I'm reviewing the code on the Dataverse side at IQSS/dataverse#9096 and plan to use this issue to list bugs and typos I find:

• typo: "aftterwards"
• "Help/Tutorial" links to https://github.com/gdcc/dvwebloader/wiki/DVWebloader---a-bulk-file-uploader-for-Dataverse which prompts the user to create a new wiki page.
• green "upload complete" when it actually failed (see screenshot below)
• API token shown by console.log
• ...

Fixed the doc-related issues. Will leave open for the code changes.
