+Add "On theme block rename" handling
+
+Whenever a theme block gets renamed, the following will now happen:
+  1. References in files with a `{% schema %}` will be updated automatically
+  2. References in template files will be updated automatically
+  3. References in section groups will be updated automatically
+  4. References in `{% content_for "block", type: "oldName" %}` will be updated automatically
