Highlighter shiki adds a trailing new line to code blocks about slidev

[KermanX]

I can't reproduce it 😭

Here is a reproduction:

1. Open up https://github.com/openscript-ch/slidev-theme/tree/repro/new-line
2. pnpm install
3. pnpm dev
4. Open slide 8

Same problem here, I'm using highlighter: shiki, and code block with triple quotes produces one extra empty line (I've replaced backticks with quotes):

'''matlab
temperature = 38
'''

This code produces two lines of code in slide, where last one is just empty line, instead of single one line of code. In early versions of slidev there was no such problem. Here's part of the package.json from previous version I've been using:

  "dependencies": {
    "@slidev/cli": "^0.42.9",
    "@slidev/theme-default": "latest",
    "@slidev/theme-seriph": "latest",
    "slidev-theme-academic": "^1.1.3"
  },

Thank you @KermanX and @antfu for fixing this so quickly!
