MDN URL per feature

[foolip]

In order to support GoogleChrome/webstatus.dev#295 we'd need a MDN URL per feature and publish it as mdn_url or similar.

We can get MDN URLs from BCD, but for most features we'll have more than one. If so we need to pick one of them, or sometimes another page that's about the feature as a a whole.

I toyed a little bit with this on this dashboard I made: https://captainbrosset.github.io/web-features-explorer/recent/
Click on a feature's Learn More link to see MDN link(s).
The code is not pretty, and it makes no attempt to have just one URL. In fact I don't think we will be able to always have just one. The code just kind of simplifies the links, and groups them by technical areas. See https://github.com/captainbrosset/web-features-explorer/blob/main/.eleventy.js

I don't think that's what you wanted here, but I thought I'd mention it anyway. This could be a solution that doesn't require maintenance.

We could quite easily generate mdn_url which could be one or more URLs, and then override it to be a single URL when that makes more sense.

I guess we could also map markdown articles in the mdn/content repo to web-feature IDs, like we do in BCD.
