Support React 19

[mnemitz]

Would it be possible to allow React 19 as a valid peer dependency for @signalwire/docusaurus-theme-llms-txt? Currently only accepts 18 in package.json

  "peerDependencies": {
    "react": "^18.0.0",
    "react-dom": "^18.0.0"
  },

I don't think the code is leveraging any features that would break with 19, but I will test to confirm. I'm also happy to raise a PR.

The website directory in the repo that utilizes the plugin is in fact on React 19, and also utilizes all the Docusaurus v4 future flags. I can confirm nothing will break. However, this seems like a reasonable request :)
