interop: add electron transport interop ping test

[p-shahi]

node.js/electron support for webrtc transport was added in https://github.com/libp2p/js-libp2p/pull/1905 & supports:

• Dialing private-to-private
• Listening private-to-private
• Dialing private-to-public

Currently blocked on the fact that all WebRTC tests are disabled: https://github.com/libp2p/js-libp2p/issues/1846

This is unblocked now. WebRTC/WebRTC Direct tests are run against node.js already but not electron.

Electron should run the same suite of transport tests as node.js.

To implement this:

1. Create an ElectronDockerfile similar to https://github.com/libp2p/js-libp2p/blob/main/interop/BrowserDockerfile
2. Build the electron container in https://github.com/libp2p/js-libp2p/blob/main/interop/Makefile
3. Create an electron-version.json similar to https://github.com/libp2p/js-libp2p/blob/main/interop/node-version.json
4. Add it to extra-versions - https://github.com/libp2p/js-libp2p/blob/main/.github/workflows/main.yml#L236
