Link features to origin trials

I think there's a way to know if an origin trial is ongoing for a feature in Chrome, likely based on chromestatus.com's API.
If so, it would be really nice to highlight features that are currently under OTs in the explorer.

Chrome's OTs should be listed here: https://chromestatus.com/api/v0/origintrials (currently broken, but should be back soon)

(some of) Chrome's OTs are now visible on the explorer, thanks to the above API, and a script that compares the spec URLs found in OTs with the spec URLs we have on our features.
Not ideal, but seems to work. See https://web-platform-dx.github.io/web-features-explorer/features/wasm-string-builtins/ as an example.

Other browsers don't have an API we can use. OTs are listed here:

• Edge: https://developer.microsoft.com/en-us/microsoft-edge/origin-trials/trials
• Firefox: https://wiki.mozilla.org/Origin_Trials

One option would be to set a reminder to go and check these pages and update the origin-trials.json file accordingly.
