Add VidWords - YouTube transcript capture

[haljishi]

What this adds

One row under General, in alphabetical position between Video Speed Controller and Vimium.

- [VidWords](https://vidwords.com/extension) - Captures the transcript of the YouTube video in the current tab and exports it as TXT, SRT, VTT or Word, including on videos whose YouTube transcript panel is missing.

• Chrome Web Store: https://chromewebstore.google.com/detail/njjmjcjjcplanbdliidknpaepifknohh

Against the guidelines in contributing.md

• Searched the list first — no existing entry for this or any other YouTube transcript extension.
• Format is [Name](link) - Description.
• Description starts with a capital, ends with a full stop, and does not begin with "A" or "An".
• General is the closest category; it already holds the video-related entries (Video Speed Controller) and product-site links such as Toast.log.

What it does

It reads captions from the page's own context rather than from a server, which is why it still works where YouTube's transcript panel is unavailable. Output is TXT, SRT, VTT or Word.

I maintain VidWords. In-browser capture is free and unlimited, no card or account needed.
