[cli] update dataset readme with the latest output (#8790)

The dataset examples are generated by version 1.1 OT stack
where the Security Policy value has length of 3 bytes but 1.2
extends it to 4 bytes.

The real problem is that spec requires that **ZERO** Key Rotation
**SHALL NOT** be allowed:
```
Key rotation period in hours. The
minimum key rotation period SHALL be
1 hour and a key rotation period of 0
SHALL NOT be allowed.
```

But the example is using ZERO.

This commit fix this by updating the examples to 1.2 version.
This commit fix also problems that incomplete TLV HEX string
(Pending Timestamp and Delay Timer are missing) are used for
setting the Pending Dataset (e.g. `dataset set pending`).
