Pinterest URLs not embedding when not .com (.es, .it...)

[alvarotrigo]

Description

Pinterest URLs that don't come from the .com domain won't be embedded. Pinterest uses a different domain for different countries and people in those countries might find it difficult to use this block.

Step-by-step reproduction instructions

For example, these URLs won't get embedded: https://www.pinterest.es/pin/320670435980314659/ https://www.pinterest.it/pin/308004062030905959/

But changing the .es and .it for .comwill make it work: https://www.pinterest.com/pin/320670435980314659/ https://www.pinterest.com/pin/308004062030905959/

Expected behaviour

Any URL coming from the existing interest domains in each country should work. Having a list of them should be enough to deal with this.

Actual behaviour

URLs won't embed if not coming from the .com domain.

I found that when you try to embed the pin, the URL http://localhost:8888/index.php?rest_route=%2Foembed%2F1.0%2Fproxy&url=https%3A%2F%2Fwww.pinterest.es%2Fpin%2F659566307946923269%2F&_locale=user (using pinterest.es in this case) returns 404. However the actual pin URL (https://www.pinterest.es/pin/659566307946923269/) returns 200.

It looks like the Pinterest embed provider supports those URLs, but the regex used in Core limits URLs to .com(.au|.mx).

@alvarotrigo, can you create a core ticket since this needs to be handled in a different repository?

Example embed - https://www.pinterest.com/oembed.json?url=https://www.pinterest.es/pin/320670435980314659/.
