57	* Enable the core Legacy Widget block in the Site Editor.

59	* On a block theme there is no classic Widgets screen, and the Site Editor
60	* does not expose the Legacy Widget block by default, so there is no UI to
61	* insert the plugin's classic widgets (Recent Jobs, Featured Jobs). Opting
62	* the block in here restores that path. Scoped to the Site Editor screen so
63	* the post/page editor is left untouched.
64	*
65	* The Site Editor registers `core/legacy-widget` itself with
66	* `supports.inserter: false`, so calling `registerLegacyWidgetBlock()` here
67	* would be a duplicate registration and log "Block core/legacy-widget is
68	* already registered". Instead, flip the inserter support flag on core's own
69	* registration via the `blocks.registerBlockType` filter.
