showLineNumber dosent work when placed at the end of the meta tags.

[beamcode]

Is this expected ? Thanks!

- Works

```tsx showLineNumbers /age/#v /name/#v /setAge/#s /setName/#s /50/#i /"Taylor"/#i
const [age, setAge] = useState(50)
const [name, setName] = useState("Taylor")
```

- Does now work

```tsx /age/#v /name/#v /setAge/#s /setName/#s /50/#i /"Taylor"/#i showLineNumbers
const [age, setAge] = useState(50)
const [name, setName] = useState("Taylor")
```

I've got a fix for this in #229

here's an example of it working when at end of metatags: https://d68419f3.rehype-pretty-example-astro.pages.dev/

rehype-pretty-code/examples/astro/src/pages/index.mdx

Line 8 in f4a806d

```elixir title="fib.ex" /palindrome/#v showLineNumbers

just need to update tests in #229 then will merge and do a release
