Deprecation warnings in 2026.6.0b0 and above (re: alias BaseTrackerEntity)

## Configuration

## Describe the bug

Changes to the device tracker entity in HA 2026.6.0b0 are generating deprecation warnings in the logs at startup:

```
Logger: homeassistant.components.device_tracker.config_entry
Source: helpers/deprecation.py:272
Integration: Device tracker (documentation, issues)
First occurred: 10:22:58 (1 occurrence)
Last logged: 10:22:58

The deprecated alias BaseTrackerEntity was used from bermuda. It will be removed in HA Core 2027.6. Use homeassistant.components.device_tracker.BaseTrackerEntity instead, please report it to the author of the 'bermuda' custom integration
```

Obviously, the component still functions perfectly in the meantime.
