[🐞] Build fails to find Qwik components when using `deno.jsonc`

Which component is affected?

Build process

Describe the bug

The build process fails to locate Qwik components when package.json is replaced by deno.jsonc.

Reproduction

https://github.com/quadratz/qwik-astro-issue-268-

Steps to reproduce

1. Make sure you have Deno installed
2. Clone this repository: https://github.com/quadratz/qwik-astro-issue-268-. (Notice that package.json has been replaced by deno.jsonc)
3. Run deno task build
4. Check the logs. You'll see could not read /package.json ... and a warning that the Qwik core bundle wasn't found.

Reproduce the failure using the linked repository and deno task build, then inspect how the build process reads package.json when only deno.jsonc exists. Done means the build locates the Qwik components and no longer reports repeated /package.json errors or a missing Qwik core bundle.
