Update Twitter oEmbed URL

[niallkennedy]

Twitter moved its preferred oEmbed URL for single Tweets from api.twitter.com to publish.twitter.com.

Update the oEmbed provider array to point at the new preferred endpoint, matching autodiscovery behavior. The ​XML response format will be removed.

Example URL:
​https://twitter.com/WordPress/status/690269689855942657

As twitter is deprecating the XML on May 1, I think this is a good fix to get in for 4.5

36197.2.diff​ adds support for moments, which are supported by the new endpoint, see ​https://dev.twitter.com/web/embedded-moments/oembed.

Update Twitter oEmbed URL.

Twitter moved its preferred oEmbed URL for single Tweets from api.twitter.com to publish.twitter.com. They also are deprecating XML responses.

Props niallkennedy.
Fixes #36197.

@ocean90 Do you want to add the moments support? Is that not covered by the current autodiscovery?

[ocean90]

@jorbin Autodiscovery works only if the page includes the link tag, ​https://twitter.com/i/moments/650667182356082688 has none. A single tweet like ​https://twitter.com/sonicadvance1/status/706219050473549824 includes one though.

@niallkennedy Is this something which Twitter is planning to implement?

[niallkennedy]

We will return an oEmbed response from the same API URL for Moment and collection URLs today. We plan to add autodiscovery.

Thanks @niallkennedy, I'm going to add support for the new URLs.

Autodiscovery doesn't work for these because wp_filter_oembed_result() filters the HTML data.
