<issue_title>Optional dependency error</issue_title>
<issue_description>### Describe the bug

I don't need to use the vue-use-monaco package, but I still get it as an error.

 Uncaught (in promise) Error: Optional dependency "vue-use-monaco" is not installed. Please install it to enable code editor features.
    getUseMonaco index.js:2511
    rejected index.js:43
18 index.js:2511:13

Do you think it shouldn't just advise you with a warning as the package is optional?
Also it would be nice the warning to appear only in dev mode and not in production.

Reproduction

Start a project without installing vue-use-monaco

Comments on the Issue (you are @copilot in this section)

@Simon-He95 Try the latest version. If vue-use-monaco is not installed, it will use preCodeNode rendering instead. Of course, you can also use a custom code_block component to override it. @zerob13 Could you please provide a minimal reproducible demo repository for this issue? It would really help us understand and troubleshoot the problem more efficiently. Thank you very much!

Fixes #41
