feat(exporter/windows): expose physical_disk collector

CHANGELOG.md

@@ -101,6 +101,9 @@ v0.39.0-rc.0 (2024-01-05)
 - `discovery.lightsail` now supports additional parameters for configuring HTTP client settings. (@ptodev)
 - Add `sample_age_limit` to remote_write config to drop samples older than a specified duration. (@marctc)
 
+- Expose `physical_disk` collector from `windows_exporter` v0.24.0 to

 ### Bugfixes
 
 - Update `pyroscope.ebpf` to fix a logical bug causing to profile to many kthreads instead of regular processes https://github.com/grafana/pyroscope/pull/2778 (@korniltsev)
