Fix: Resolve Java warnings and improve error handling

This commit addresses several warnings found in the Java code:

- Adds a suggestion to update the Bazel workspace configuration when the  is missing in .
- Enhances the error message for emulator listing failures in  to include a hint about checking the Android SDK configuration.
- Increases the number of retry attempts for the Flutter daemon before displaying a warning to the user in , potentially reducing unnecessary notifications for transient issues.
- Modifies the exception handling in  to log the specific exception type and message, aiding in debugging.

These changes aim to improve the robustness and user experience of the Flutter IntelliJ plugin.
