Remove unsupported Hulu oembed provider

[talldanwp]

As mentioned in ​https://github.com/WordPress/gutenberg/issues/23920, Hulu no longer seems to support their oembed service.

It seems like the best option would be to drop Hulu support similar to previous unsupported providers in #45399.

Added Hulu to 'no longer supported providers' from 'supported providers' list.

@talldanwp let me know if there are any changes. Thanks!

I'm thinking this is a good bug to squash for 5.5. Moving into the milestone to explore.

It is removing a service that will no longer work as expected, and not adding or changing functionality in any way.

@talldanwp If we chose to remove oEmbed support for Hulu in 5.5, could the Hulu oEmbed block be disabled and backported?

[talldanwp]

Hey @desrosj, sounds good, it looks like the 'Backport to WP Core' label has been added to the merged pull request for removing the block (​https://github.com/WordPress/gutenberg/pull/23984), so we should be good to go for landing both changes in 5.5.

In 48512:

Embeds: Remove Hulu from the list of supported oEmbed providers.

The oEmbed service for Hulu no longer works and appears to have been silently disabled.

Props tacitonic, talldanwp, youknowriad, bph.
Fixes #50676.
