Add section to debugging.md to explain that you can also use IDEs debug (#2146)

* Add section to debugging.md to explain that you can also use IDEs to debug

In firefox-devtools/vscode-firefox-debug#393 I've found out, that the possibility of debugging extensions using an external program is not even mentioned at all here.

I guess at least such a minimal version like this would be useful. The way how to do it is then documented there.

* docs: properly make use of this capture thing (I hope)

* Feedback update

+## Debugging with an external development environment (IDE)
+
+Mozilla provides a [Debug Adapter for Firefox](https://www.npmjs.com/package/firefox-debugadapter) that implements the [Debug Adapter Protocol (DAP)](https://microsoft.github.io/debug-adapter-protocol/). This adapter enables debug integration with any IDE that supports DAP.
+
+At the time of writing, September 2025, these integrations are available:
+
+- Visual Studio Code [Debugger for Firefox](https://marketplace.visualstudio.com/items?itemName=firefox-devtools.vscode-firefox-debug)—this extension is maintained by the [Firefox DevTools](https://marketplace.visualstudio.com/publishers/firefox-devtools) team.
+- [Eclipse Wild Web Developer : 🌐 Web dev in Eclipse IDE 🌘](https://github.com/eclipse-wildwebdeveloper/wildwebdeveloper/)
 
+In addition, other DAP adapters have been reported to work, such as debugging in [Neovim](https://neovim.io/), using [nvim-dap](https://github.com/mfussenegger/nvim-dap).
