Refactor JetBrains module for air-gapped support

- Improved logic for handling air-gapped environments by utilizing
  fallback mechanisms in JetBrains integrations.
- Updated parameters and default settings to align with the new
  connectivity conditions, ensuring robustness in varied network
  scenarios.
- Expanded tests to validate custom configurations even when API access
  is restricted, confirming consistent behavior across setups.

+
+**How it works:**
+
+- The module first attempts to fetch the latest build numbers from the JetBrains API
+- If the API is unreachable (network timeout, DNS failure, etc.), it automatically falls back to the build numbers specified in `ide_config`
+- This ensures the module works in both connected and air-gapped environments without configuration changes

 ### Version Resolution
 
-- Build numbers are always fetched from the JetBrains API for the latest compatible versions
-- `major_version` and `channel` control which API endpoint is queried
+- Build numbers are fetched from the JetBrains API for the latest compatible versions when internet access is available
+- If the API is unreachable (air-gapped environments), the module automatically falls back to build numbers from `ide_config`
