update schemas to reflect what asset_tracker_v2 is actually sending

[coderbyheart]

This aligns the schemas to match the data sent by asset_tracker_v2.

Question remains where this mismatch should be fixed, it could also be fixed on the firmware side.

this has been a string for a long time.
ATv2 has its own implementation, which is a number.
i have no preference, other than that all code in NCS is aligned.

ICCID, along with IMSI and UICC mode, has been reported in the "simInfo" section for a long time.
again, no preference, but all NCS code should be aligned.

the modem_info library provides a string for this value.
the nrf_cloud library reports this value as a string.

Current asset_tracker_v2 sends number:

"roam": {
          "v": {
            "band": 12,
            "nw": "LTE-M",
            "rsrp": -119,
            "area": 34635,
            "mccmnc": 310410,
            "cell": 141255696,
            "ip": "10.165.115.123",
            "eest": 7
          },
          "ts": 1681909040890
        },

this is a breaking change for fw apps using modem_info library or nrf_cloud library to update the shadow.

@coderbyheart. The NCS change notes says that you provide BATTERY and not VOLTAGE appid. I do not see that change here? Or should there be new PR

Also, the BATTERY level seems to be from PMIC. Does all our Thingys and DKs contain the needed PMIC?

I haven't added this, yet.

I don't know.

Added.
