[Bug]: code blocks in lists with negative margin

### What happened?

Code blocks within unnumbered list items (not within numbered list items) show a negative margin: they not only do not respect the list indentation, they also rendered are left of the regular text outside of the list.

culprit seems to be https://github.com/adityatelange/hugo-PaperMod/blob/d3768854d00ad003b0a8dbdba254ce9224377a01/assets/css/common/md-content.css#L122. A similar problem was addressed in https://github.com/adityatelange/hugo-PaperMod/pull/154, but did not touch this line.

I am unsure how to fix this, but removing the whole block
```
.md-content ul pre {
margin-inline-start: calc(var(--gap) * -2);
}
```
fixes the problem for me.

### Steps to reproduce

render
````
regular text
- list item 1
- list item 2
some more text
```
Some code
```
````

This, in papermod, sets a negative margin for the text block, while in fact it should be positive (and match the one of the rest of the item text).
