MWPW-141870: Update seotech-video-url API endpoint

[hparra]

Update seotech-video-url feature to use new version of API endpoint behind adobe.com.

Resolves: MWPW-141870

Context

I update the implementation of the seotech-video-url feature to use a new version of seotech API endpoint which allows for proper caching and sits behind adobe.com. We now parse video urls locally first and call the endpoint if url is supported. There are no visible changes to the user.

I also update the seotech README for future developers.

Testing

Unit

I updated all unit tests and added extensive tests for regex.

E2E

Use the following snippet in dev console to confirm added VideoObject JSON-LD on each non-error page:

Array.from(document.querySelectorAll('script[type="application/ld+json"]')).map((el) => JSON.parse(el.innerText))
