proxmox_disk failing to recognize issues in operations

[castorsky]

Summary

In reviewing PR #7969, I discovered the root cause of the behavior:

• the proxmox_disk module currently uses the PUT method to call the resize function, assuming it operates synchronously;
• starting with version 8, the Proxmox team changed the resize function to an asynchronous operation that returns a task ID:
  • Proxmox Bug;
  • API Breaking Changes Announcement.

I plan to submit a PR to update the resize functionality in the proxmox_disk module to handle the new asynchronous behavior. However, this change will break compatibility with older versions of Proxmox VE.

Considering the discussion in #9199, I hope the community will agree that overloading the code to support older, unsupported versions is not ideal. Feedback on this approach is welcome.
