Request: Add `requires_plugins` to the Update Check API.

[costdev]

With the addition of Plugin Dependencies in WordPress Core, it's possible that a dependent plugin may release an update that adds or changes its dependencies.

If a plugin update increases the WordPress/PHP version requirements, WordPress Core notifies the user after checking requires_php, for example, and the update is unavailable and WordPress until are requirements are met.

requires_plugins is already added to the Plugins API when querying information about a plugin. Can we also add it to the Update Check API? Doing so will also enable WordPress Core to prevent auto-updates of plugins, ensuring trust in the auto-updater.

In 13241:

Plugin Directory: API: Prepare to include the Plugin dependencies in the update api.

See #7483, #6921.

This should be present in the API response now, give it a test and let me know if it seems to work for you.

Note: It's only present if there's an update for the plugin available.

@dd32 Confirming that requires_plugins appears in the API response when a plugin update is available.

Thanks!
