feat: fix: add test skips for custom_pages.assets, fix YAML syntax

* fix: add test skips for custom_pages.assets, fix YAML syntax

custom_pages.assets: all 5 methods (create, update, list, delete, get)
fail because generated tests don't pass the required zone_id argument.

Also fixes a YAML syntax error on line 89 (two key-value pairs
merged onto one line).
