Describe the Bug

The Getting Started section in the README.md of the chanfana-openapi-template contains an outdated/incorrect example command for creating a new project using C3.

Current text (incorrect):

Outside of this repo, you can start a new project with this template using C3 (the create-cloudflare CLI):
npm create cloudflare@latest -- --template=cloudflare/templates/openapi-template
A live public deployment of this template is available at https://openapi-template.templates.workers.dev/
...

This points to cloudflare/templates/openapi-template, which is not the correct path for this template.

Expected / Correct command:

npm create cloudflare@latest -- --template=cloudflare/templates/chanfana-openapi-template

Why this matters
Users following the README will scaffold the wrong template (likely an older or different OpenAPI variant), leading to confusion and wasted time. Updating this one line would make the template immediately usable via C3 as intended.

Suggested fix
Replace: --template=cloudflare/templates/openapi-template with --template=cloudflare/templates/chanfana-openapi-template

Additional context
Repository: https://github.com/cloudflare/templates/tree/main/chanfana-openapi-template
File: README.md
No other changes needed — the rest of the README looks accurate and helpful.

Thanks for maintaining these excellent templates — this is a very small tweak that would improve the onboarding experience significantly!
