[PATCH docs 0/6] container documentation updates

[666Goofy666]

From: 666Goofy666 <666goofy666@proton.me>

hi,
here some commits to update the container doc page.
the main one is the fix for network interfaces.
others are separate changes that I found while reviewing
the documentation, so you can cherry-pick them individually.

- network interfaces: info in the ticket #7852
- snapshots: just fixing a typo in the example
- cgroups and systemd: the code use 232, probably beceause
 systemd start implement in v230 and finish in 232
- configuration keys for LXC: settings have changed in LXC 2.1
 the change in code to depreceated is made in
 pve-container: `108c6cab98b091f82b725c98f198bada9752ccdc`
- cgroups memory: PVE 9 uses cgroups v2 so the settings changes
 v1 `memory.memsw.limit_in_bytes` represent memory + swap.
 v2 `memory.swap.max` represent only the swap,
 pve-container: `722a07704836d61a131af8b982d208ccfe6ce336`
- mount points just typo

best regards,

[PATCH docs 3/6] pct: cgroups: fix systemd supported version

[666Goofy666]

From: 666Goofy666 <666goofy666@proton.me>

Although systemd introduced cgroup v2 support in version 230, code
(unified_cgroupv2_support) requires 232 or newer to ensure broader
controller support.

[PATCH docs 5/6] pct: memory: change to cgroup v2

[666Goofy666]

From: 666Goofy666 <666goofy666@proton.me>

PVE9 no longer uses cgroups v1, reflect cgroup v2 memory and swap
limits, where swap is defined independently from the memory limit.
