docs(google): correct GCP CPI feature support matrix

[neddp]

Native Disk Resize has been supported since v41.0.0 (Nov 2021). Native Disk Update (snapshot-based disk type migration) has been supported since v50.1.3 (May 2026).

Walkthrough

The Google CPI documentation now marks Native Disk Resize as supported from v41.0.0 and Native Disk Update as supported from v50.1.3. It adds references for both releases. Multi-CPI remains marked as not supported. The table formatting was also adjusted.

Priority: ⬇️ Low

Merge Risk: 🔵 Low · up to 062b4

Readers may expect replacement-disk and orphan cleanup behavior when supported native update can resize the existing disk in place. The localized documentation correction should be made before or with the change.

In `@content/google.md`:
- Around line 44-50: The persistent-disk migration guidance around the
referenced statement must document the Google CPI native disk update exception:
when director.enable_cpi_update_disk=true,
director.enable_cpi_resize_disk=false, and only the disk size increases, the
existing disk is resized in place, retains its CID, and is neither copied nor
orphaned. Qualify the existing migration and orphan-disk guidance accordingly;
leave the Google support table unchanged.
