fix(sfc-playground): resolve autosave conflict issue

[phk422]

I discovered that after upgrading from @vue/repl@4.4.0 to v4.4.2 #11939, there were issues with autosave conflicts and failure. The cause is that some default operations for autoSave were added in @vue/repl@4.4.1, which led to changes in the property. This PR aims to resolve the conflict.
