Editing an existing topic or collection

I'm suggesting these edits to an existing topic or collection:

• Content (and my changes are in index.md)

Adding Wails as a related topic for Electron and Tauri

Curating a new topic or collection

• I've formatted my changes as a new folder directory, named for the topic or collection as it appears in the URL on GitHub (e.g. https://github.com/topics/[NAME] or https://github.com/collections/[NAME])
• My folder contains a *.png image (if applicable) and index.md
• All required fields in my index.md conform to the Style Guide and API docs: https://github.com/github/explore/tree/main/docs

Wails is a viable alternative to Electron and Tauri that offers advantages over both.

Add Wails as a curated topic and update related topics
