Add docusaurus-plugin-copy-page-button

[portdeveloper]

Summary

Adds docusaurus-plugin-copy-page-button to the PlayCanvas developer site so readers can copy any documentation page as clean markdown — useful when piping engine/editor docs into ChatGPT, Claude, Perplexity, or Gemini for help with PlayCanvas scripts, scenes, or shader work.

The plugin auto-injects a small "Copy page" button + dropdown into the doc page's table-of-contents area. The dropdown offers:

• Copy as markdown
• View as markdown
• Open in ChatGPT / Claude / Perplexity / Gemini

Complements existing llms.txt corpus export

The repo already has a custom utils/plugins/docusaurus-plugin-llms.mjs that generates /llms.txt and /llms-full.txt at build time — those are great for whole-corpus consumption. This plugin is the per-page complement: a reader on a specific page can grab just that page's markdown for a focused AI conversation. It doesn't replace or duplicate the existing exports.

Adoption

The plugin currently ships on the docs sites for React Native (just merged via facebook/react-native-website#5085), Puppeteer, Arbitrum, Cardano, Sui, Ethereum execution-apis, and several others — full list in the project README.
