Missing consumer-rules.pro

### Describe the bug

The NFC and Barcode scanner plugin refer to a proguard file that is not present in the source code. I am not sure if this is generated during build time but it is not shipped in the resulting crate.
[onsumer-rules.pro](https://github.com/tauri-apps/plugins-workspace/blob/114e9025377a69d6d47f6b2b54212ae98e47998e/plugins/barcode-scanner/android/build.gradle.kts#L14)

I am unsure if there are other plugins affected. Using more modern android toolchains (gradle 9) will refuse to compile since the files can not be found.

### Reproduction

_No response_

### Expected behavior

A consumer-rules.pro should be present in the downloaded crate or at least during build time.
