Updates the internal `shiki` syntax highlighter to `shikiji`, an ESM-focused alternative that simplifies bundling and maintenance.
There are no new options and no changes to how you author code blocks and syntax highlighting.
**Potentially breaking change:** While this refactor should be transparent for most projects, the transition to `shikiji` now produces a smaller HTML markup by attaching a fallback `color` style to the `pre` or `code` element, instead of to the line `span` directly. For example:
Before:
```html
<code class="astro-code" style="background-color: #24292e">
<pre>
<span class="line" style="color: #e1e4e8">my code</span>
</pre>
</code>
```
After:
```html
<code class="astro-code" style="background-color: #24292e; color: #e1e4e8">
<pre>
<span class="line">my code<span>
</pre>
</code>
```
This does not affect the colors as the `span` will inherit the `color` from the parent, but if you're relying on a specific HTML markup, please check your site carefully after upgrading to verify the styles.
