Module proxmox_kvm restarted state bug fix (#6773)

* Change proxmox_kvm restart to use new method

Previously, the `restarted` state used both stop and start vm functions to restart a vm.
This change introduces the a new function that utilizes the proxmox reboot endpoint instead for a more reliable method of restarting a vm.

* Create 6773-proxmox_kvm-restarted-state-bug-fix.yaml

* Fix typo

* Add link to PR

* Chanel log fragment formatting changes

* Move try/catch to `restart_vm` function

* Update changelogs/fragments/6773-proxmox_kvm-restarted-state-bug-fix.yaml

+  - proxmox_kvm - ``restarted`` state did not actually restart a VM in some VM configurations. The state now uses the Proxmox reboot endpoint instead of calling the ``stop_vm`` and ``start_vm`` functions (https://github.com/ansible-collections/community.general/pull/6773).
