Upgrade chroma to v2.3.0 (#21259)
The behaviour of `PreventSurroundingPre` has changed in alecthomas/chroma#618 so that apparently it now causes line wrapper tags to be no longer emitted, but we need some form of indication to split the HTML into lines, so I did what yuin/goldmark-highlighting#33 did and added the `nopWrapper`. Maybe there are more elegant solutions but for some reason, just splitting the HTML string on `\n` did not work. Co-authored-by: wxiaoguang <[email protected]>
