`CodeBlockParser::parse()` stored the fenced code info string in
`options['caption']` via `withOptions()`, but nothing ever read that
value — `CodeNode::getCaption()` returns the typed `$caption` property,
not `getOption('caption')`. As a result, `CodeNode::getLanguage()`
always returned `null` for markdown code blocks, producing
`class="language-"` in the rendered HTML and preventing syntax
highlighting.
Replace the dead `withOptions(['caption' => ...])` call with
`setLanguage()` using `getInfoWords()[0]` from the CommonMark
`FencedCode` node, matching both the RST parser's behavior
(`CodeBlockDirective`) and league/commonmark's own `FencedCodeRenderer`.
