Unified Extensibility APIs in WordPress 6.6

[vikrampm1]

WordPress 6.6 unified the different slots and extensibility APIs between the post and site editors.

Please check the extension and validate the following along with the version bump issue:

• [ ] Check if the plugin is integrating twice, once with wp.editPost and once using wp.editSite
• [ ] If yes, then update those to use wp.editor global variable (@wordpress/editor package or wp-editor script handle) as noted here https://make.wordpress.org/core/2024/06/18/editor-unified-extensibility-apis-in-6-6/

@vikrampm1 While working on this, I found that plugin is using extensibility component only from @wordpress/edit-post package. I could not find any references from wp.editSite or @wordpress/edit-site package.
