Fixed: Correct publication of Maven libraries after update of Gradle to 9.2.1

- After https://github.com/termux/termux-app/pull/3619, unfortunately this error began to occur when one attempts to use the [Publication to Maven Local guide](https://github.com/termux/termux-app/wiki/Termux-Libraries#forking-and-local-development) to compile all Termux APKs entirely from source, which previously worked:

```
> Task :app:processDebugResources FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.
> A failure occurred while executing com.android.build.gradle.internal.res.LinkApplicationAndroidResourcesTask$TaskAction

```

- This PR fixes that error by using `components.default` in the `publications` block instead of `components.findByName('release')` and adding a `publishing` block to the `android` section of the `build.gradle` of each affected library, in accordance with https://developer.android.com/reference/tools/gradle-api/9.1/com/android/build/api/dsl/PublishingOptions and https://stackoverflow.com/a/71366104. `components.release` no longer works, but testing indicates that `components.default` works.
