Blockquote in wikipedia is not handled

### Is there an existing issue outlining your problem?

- [x] I am using the latest version of the provided userstyle.
- [x] I have searched the existing issues and they do not solve my problem.

### What userstyles are you seeing the problem on?

lbl:wikipedia

### Describe your problem.

In the Wikipedia, `blockquotes` is not handled. Here is an example on how its currently looking.

as an temporary fix I have added following code
```
blockquote {
background-color: @surface0 !important;
border: 2px solid @surface2 !important;
color: @text !important;
}

blockquote.templatequote {
border: none !important;
border-left: 1px solid @surface2 !important;
max-width: 90% !important;
margin: 5px auto !important;
background-color: @base !important;
}
```

But I think it would get overridden when you push any update, also I am not a designer, so I would really prefer a cleaner upstream solution.

Thanks.

Start with the Wikipedia userstyle identified by `lbl:wikipedia` and search its source for existing `blockquote` rules. Compare the current rendering with the CSS shown in the issue, then verify in Firefox that Wikipedia blockquotes have the intended styling and remain correct after a userstyle update.
