@phpbits @dkotter @peterwilsoncc looks like we can also update this as well?

simple-podcasting/assets/js/create-podcast-show.js

Lines 19 to 20 in 17287bc

	// Once WordPress 6.6 becomes our minimum, change this back to `import { PluginDocumentSettingPanel } from '@wordpress/editor';`.
	const PluginDocumentSettingPanel = wp.editor?.PluginDocumentSettingPanel ?? ( wp.editPost?.PluginDocumentSettingPanel ?? wp.editSite?.PluginDocumentSettingPanel );

Yep, no longer need that shim if we bump our minimum past 6.6. Likely have this in other plugins as well if I'm remembering correctly

I've updated the import in 34f5314.

As we're bumping the minimum supported version of WP, this will require a release as it modifies the PHP file. I've moved the header for the minimum version in 39eb978 so we can do out of release cycle updates in the future.

LGTM and tests well.
