Fix new Proxmox Volume handling (#8646)

* proxmox(fix): volume string builder

Half of the string was incorrectly discarded

* proxmox(fix): remove string conversion of values

 - Also converted `None` values into strings
 - Clashed with non-`str` values in documentation

* proxmox: add changelog fragment

* proxmox(fix): remove old & unused imports

* proxmox(fix): correctly turn maps into lists

* Update changelogs/fragments/8646-fix-bug-in-proxmox-volumes.yml

Co-authored-by: Felix Fontein <felix@fontein.de>

* Update plugins/modules/proxmox.py

+  - proxmox - removed the forced conversion of non-string values to strings to be consistent with the module documentation (https://github.com/ansible-collections/community.general/pull/8646).
+  - proxmox - fixed an issue where the new volume handling incorrectly converted ``null`` values into ``"None"`` strings (https://github.com/ansible-collections/community.general/pull/8646).
+  - proxmox - fixed an issue where volume strings where overwritten instead of appended to in the new ``build_volume()`` method (https://github.com/ansible-collections/community.general/pull/8646).
