docs: split Prerequisites by version — v3.0 needs no SSH keys or pre-created targets

v3.0 is fully API-driven: no SSH keys, no pre-created iSCSI targets.
v2.x still requires both. Separating them prevents confusion for users
on either version and removes incorrect guidance from the v3.0 path.

## Prerequisites
Before installing, ensure the following are in place on your **Proxmox VE node**:
### v3.0 (upcoming)
v3.0 is a fully API-driven custom storage plugin. No SSH keys required.
1. On **TrueNAS**, ensure the iSCSI service is running and an iSCSI **portal** and **initiator group** are configured. The plugin creates per-VM iSCSI targets automatically — you do not need to pre-create a target.
2. Generate a TrueNAS API key:
- TrueNAS SCALE: *System Settings → API Keys → Add*
- TrueNAS CORE 13: *gear icon (top-right) → API Keys → Add*
Copy the key — you will need it during storage configuration in Proxmox.
### v2.x (current stable)
1. **SSH keys** configured between Proxmox and TrueNAS — required for ZFS pool listing by the Proxmox core (see the [Proxmox wiki](https://pve.proxmox.com/wiki/Storage:_ZFS_over_iSCSI), section starting with `mkdir /etc/pve/priv/zfs`).
2. On **TrueNAS**, an iSCSI target and initiator group must exist and be configured. The plugin manages extents and target-to-extent mappings, but the target itself must be pre-created.
2. On **TrueNAS**, an iSCSI **target** and **initiator group** must exist and be configured. The plugin manages extents and target-to-extent mappings, but the target itself must be pre-created.
3. On **TrueNAS SCALE** or **TrueNAS CORE 13+**, generate an API key:
- TrueNAS SCALE: *System Settings → API Keys → Add*
- TrueNAS CORE 13: *gear icon (top-right) → API Keys → Add*
Copy the key — you will need it during storage configuration in Proxmox.
