Update admin diagnostics

Added a check if the templates are overridden and return which specific folder, `admin`, `email` or `scss`.
This way we could more quickly point users to possible outdated templates which they are using.

Also updated the Support String to use some emojis so we should be able to quicker see if there is something wrong.
Just checking `true` or `false` could be difficult sometimes, and sometimes what we had as `false` wasn't bad either.

Also adjusted the eslint comments so it will work with the latest version of eslint.
