facts: Detecting NVME partitions under Linux (#39730) (#39804)

* facts: Detecting NVME partitions under Linux (#39730)

In the current state of the code, the nvme partitions are returned as empty as in :
        "ansible_devices": {
            "nvme0n1": {
                "model": "SAMSUNG MZVLW256HEHP-000L7",
                "partitions": {},

The parsing of the /sys/block/<diskname> try to find a disk named like :
    <diskname><x> as in sda1 for sda

But in the nvme context, the partition of nvme0n1 is named nvme0n1p1.
This add a possible 'p' between the diskname and the partname.

This patch simply add the option of having a 'p' between the diskname
and the partname.

The patch works on my host :
                "model": "INTEL SSDPEDMD400G4",
                "partitions": {
                    "nvme0n1p1": {
                         ...
                        "size": "93.13 GB",
                    }

* Use a more exact regex (#39811)

The pattern we're matching can have zero or one p.  Be more careful to
match exactly that.
