fix: fall back to project root repositories.gradle

[erisu]

Motivation and Context

Not all subprojects will have the repositories.gradle so therefore trying to apply repositories.gradle will fail.

Description

This PR updates the logic to check if the repositories.gradle exists and if it does not, fallback and use the repositories.gradle that is in the project root directory.

Testing

• npm t
• cordova build android with a plugin that has a subproject.

Checklist

• I've run the tests to see all new and existing tests pass

@goffioul I saw your #1179 (comment) about an issue that appeared in that PR. The issue was where the repositories.gradle file is missing for subproject.

I went ahead and created this PR that should resolve the issue. I followed based on your comments. If the file is missing, it will fall back to the project's root repositories.gradle.

Sorry for the slow response. Since the comment was in a merged PR, I missed it.

If you have a project where you could test with these changes, that would be great.

This PR's branch is based on the current master branch, which means it contains Cordova-Android 10.x. If your project does not support Cordova-Android 10 yet, you might have to cherry-pick the commit. I am not positive if this fix will be back ported to 9.1.x, but there might be a chance.

I will merge this in on Monday with or without a review.

The default project build successfully.

I tested with an only plugin that I could find that added a subproject. Without the PR, It showed the repository error, but with this PR, the repository error was fixed/gone. I couldnt fully test the build because the plugin itself was 4+ years old, unmatained, and used libraries that doesnt work anymore with the current Android SDK & Gradle Build.
