Define Bazel IJ `workspace_type` as `java`.

This improves the default setup when using Android Studio for developing Bazel. This field controls the project structure to use the Java SDK instead of requiring
an Android SDK via `android_sdk_platform`, and avoids running into other Android-specific issues.
