なぜエラーが発生しているのかわかりません。
(<unknown>): found a tab character that violate indentation while scanning a plain scalar at line 93 column 13 -e LANG=en_US.UTF-8 YAML 構文エラーです。containers/*.yml 設定ファイルを確認してください。

It’s probably because you have included a tab rather than spaces. And hence, it’s not indented correctly.

My recommendation is that you delete app.yml, run discourse-setup again.

Then, copy and paste the first plugin line and edit it by removing the github address and pasting in the new one.

You didn’t ask, but it is almost certainly a bad idea to install all of those plugins.
