What is it mean? The template will be published?

No, previously, the version of @rslib/core in template is a fixed version like ^0.0.15 which is wrong. I should be workspace:* as before. workspace:* will be replaced to the correct vesion in runtime.

Inside create-rstack, we just need to ensure reserve workspace:* in template before create-rstack execute.
